Steel: Price and Policy Issues

[Excerpt] The rapid growth of steel production and demand in China is widely considered as a major cause of continued high steel prices and prices of teelmaking inputs. Steel companies have achieved much greater pricing power, in part through an ongoing consolidation of the industry. High prices persist, despite the revocation in 2003 of President Bush’s broad safeguard order on imports. U.S. steel production in 2006 was 108 million tons. The integrated side of the industry continues to lose share domestically to the minimills. Imports rebounded in 2006 to reach the highest tonnage level ever, though they declined in 2007. Input prices, especially ferrous scrap and iron ore, remain high, meaning higher costs, which have been largely passed along to industrial consumers. China now produces 40% of the world’s steel and is the world’s largest steelmaker and steel consumer. This contributed to a large global increase in demand for both steel and steelmaking inputs. China has become a large net exporter as well. In 2006, its steel exports to the U.S. market more than doubled, and it became the second-largest import source. Congress became increasingly concerned over allegedly unfair trade competition from China, and has considered many proposals to deal with these issues. In the 110th Congress, bills were introduced to allow penalty tariffs to offset a country’s manipulation of its currency exchange rate for trade advantage. The Commerce Department undertook a countervailing duty case against China, and the U.S. government also brought a case in the World Trade Organization against China over subsidies, including subsidization of steel exports. The U.S. steel industry sponsored in 2007 a report that detailed alleged government subsidies to the Chinese industry. The U.S. International Trade Commission (ITC) has terminated some trade remedy cases and orders against imported steel products. But in other cases, orders have been upheld, and new cases are proceeding. President Bush decided in a China safeguard case not to provide relief for domestic producers of steel pipe, despite a positive ITC determination. The Byrd Amendment, under which domestic steel producers receive distributions of trade remedy duties, was repealed by P.L. 109-171, and is no longer in effect from October 1, 2007. Internationally, the Organization for Economic Cooperation and Development has abandoned the effort to achieve an international agreement to ban subsidies for steel mills. In April 2006 the World Trade Organization, (WTO) Appellate Body ruled against the “zeroing” methodology used by the U.S. Commerce Department in calculating dumping margins

Lightweight design of a suspension arm by friction stir welding

The research seeks initially to investigate why a greater shift to lightweight technologies for suspension design has not occurred already over the mass market vehicle sector. It outlines the 'knock-on' benefits of lightweight design and identifies roadblocks which hinder progress. Recent annual metrics of vehicle performance related to mass are investigated. Focusing on individual areas of the suspension, benchmarking identifies the best practice amongst current designs. Manufacturing and process engineering strategies are proposed to support the development of lightweight products with considerably improved environmental acceptability.MIG (Metal Inert Gas) welding, universally accepted as the default joining technology in this field, was found to be restrictive to progress due primarily to detrimental effects on metallurgical, dimensional and process variation on both steel and aluminium products. The latest construction materials were reviewed for suspension application, but the focus remained on proposing light weighting solutions for material generically available in economic volumes today, but with new joining technologies to overcome current restrictions in using less of these materials for each component. Following a full review of the joining technologies available for automotive suspension construction, friction stir welding (FSW) was proposed as an alternative joining technology, with FSW replacing MIG in conjunction with extruded aluminium materials. This removed the barriers incumbent in the use of MIG, which demands a more conservative, heavier design to ensure adequate service lifetime. Design concepts were engineered to take maximum advantage of the strategy of aluminium, extrusions, assembled with friction stir welding. Several viable designs were conceived, from which two were developed and compared. The optimum design was then carried forward into a manufacturing feasibility stage. The extrusions were developed for ease of manufacture, and friction stir welding trials progressed on coupons (plain plates) to ensure that the process was viable. Aluminium in the soft and hardened conditions in different thicknesses and joint configurations were successfully friction stir welded during the trial. Future work would develop the extruded aluminium arm further, into the prototype phase, with sample extrusions being manufactured, FSW welded and assembled. Prototypes would then be rig tested to ensure mechanical and durability performance prior to vehicle trials. There are also possibilities in developing high strength thin wall multi-phase steel solutions, utilising Friction Stir Spot Welding (FSSW). This welding technology enhances the selection of high strength steels, as minimal strength is sacrificed during the joining operation

FDI Outflows from India: An Examination of the underlying Economics, Policies and their Impact

This paper discusses the trends in India's outward FDI over the last decade and then attempts to identify the driving factors for the same. The aim is to provide policy makers with insights regarding levers which would help in encouraging FDI outflows and to stimulate further research in foreign investment from emerging economies. The analysis is based on 287 instances of foreign investment from India by top Indian companies across 17 sectors. The paper draws on the "eclectic" paradigm to study the impact of ownership, location and internalization variables on India's foreign investment. A sector wise analysis of mode of entry, intent of entry and geographic concentration has been performed. At an aggregate level, it has been found that acquisitions have been the predominant mode of entry for Indian firms investing abroad and seeking new markets the primary intent of investment. A regression model was also developed to understand the impact and relative importance of owndership variables such as distribution system, need for resources, factor of production, post sales service requirement, presence of IP and brand on foreign investment from India. It was found that high distribution expenses and need for resources had a very positive influence on foreign investment. The paper also discusses the key policy changes that impacted outward FDI from India in the last decade and relationship of outward FDI with other macroeconomic indicators such as GDP and Fischer Open Differential.

China’s Steel Industry and Its Impact on the United States: Issues for Congress

[Excerpt] The rise of China’s steel sector, along with other manufacturing industries, presents issues beyond trade law enforcement. China’s quest for industrial raw materials is having considerable effect on global demand and supply, and as a result, the prices and availability of such inputs. China’s restrictions on exports of some raw materials, allegedly, lower the cost of such raw materials in the home economy, while increasing global prices of these products (or diminishing global supply), thereby producing an unfair advantage in some manufacturing industries. Amid the rising trade cases against various Chinese steel imports, Congress became increasingly concerned over alleged unfair trade competition from China. In August 2010, legislative measures were introduced in the Senate (S. 3725), while a set of measures focusing on illegal import practices were proposed by the U.S. Commerce Department, both aiming to continue the rigorous and more effective enforcement of U.S. trade laws. This report provides an overview of China’s steel industry and discusses the issues and implications with regard to the U.S. steel sector

Homotopy classification of ribbon tubes and welded string links

Ribbon 2-knotted objects are locally flat embeddings of surfaces in 4-space which bound immersed 3-manifolds with only ribbon singularities. They appear as topological realizations of welded knotted objects, which is a natural quotient of virtual knot theory. In this paper we consider ribbon tubes and ribbon torus-links, which are natural analogues of string links and links, respectively. We show how ribbon tubes naturally act on the reduced free group, and how this action classifies ribbon tubes up to link-homotopy, that is when allowing each component to cross itself. At the combinatorial level, this provides a classification of welded string links up to self-virtualization. This generalizes a result of Habegger and Lin on usual string links, and the above-mentioned action on the reduced free group can be refined to a general "virtual extension" of Milnor invariants. As an application, we obtain a classification of ribbon torus-links up to link-homotopy.Comment: 33p. ; v2: typos and minor corrections ; v3: Introduction rewritten, exposition revised, references added.

Implications of restructuring and privatisation for competitiveness and perfomance:two Brazilian steel companies

The thesis examines the effects of the privatisation process on productivity, competitiveness and performance in two major Brazilian steel companies, which were privatised in between 1991 and 1993. The case study method was adopted in this research due to its strengths as a useful technique allowing in-depth examination of the privatisation process, the context in which it happened and its effects on the companies. The thesis has developed a company analysis framework consisting of three components: management, competitiveness/productivity and performance and examined the evidence on the companies within this framework.The research indicates that there is no straightforward relationship between privatisation, competitiveness and performance. There were many significant differences in the management and technological capabilities, products and performance of the two companies, and these have largely influenced the effects of privatisation on each company. Company Alpha's strengths in technological and management capabilities and high value added products explain strong productivity and financial performance during and after privatisation. Company Beta's performance was weak before the privatisation and remained weak immediately after. Before the privatisation, weaknesses in management, commodity type low value added products and shortage of funds for investment were the major problems. These were compounded by greater government interference. Despite major restructuring, the poor performance has continued after privatisation largely because the company has not been able to improve its productivity sufficiently to be cost competitive in commodity type markets. Both companies state that their strategies have changed significantly. They claim to be more responsive to market conditions and customers and are attempting to develop closer links with major customers. It is not possible to assess the consequences of these changes in the short time that has elapsed since privatisation but Alpha appears to be more effective in developing a coherent strategy because of its strengths. Both companies accelerated their programme of organisational restructuring and reducing the number of their employees during the privatisation process to improve productivity and performance. Alpha has attained standards comparable to major international steel companies. Beta has had to make much bigger organisational changes and cuts in its labour force but its productivity levels still remain low in comparison with Alpha and international competitors
