BALIGA Steel Wars: A Battle for the Future of American Steel In late 2001 the United States Trade Representative (USTR) submitted a request to the U.S. International Trade Commission (ITC) to determine if the U.S. steel industry was seriously injured or threatened with serious injury as a result of recent increases in steel imports to the United States. This request was submitted under Section 201 of the Trade Act of 1974. The request followed months of petitioning by the U.S. steel industry

Sergio Galazia Mr. Flick College Writing II-8:00 23 September 2012 The Rise‚ The Fall‚ and the Rebirth of Youngstown’s Steel Industry Youngstown Ohio was once a booming steel production city located in Mahoning County just west of the Pennsylvania border. Many young adults who were raised in or around Youngstown can remember hearing about “the good old days” or back when “the mills were up and running.” It was a much different town then. Basically every family from Youngstown had at

U.S. Steel industry. What conclusion can you draw from this? Degree of Rivalry: Mini mills were being used by the foreign competition which mean they were able to produce steel at less expensive rates passing that on ot their customers. Barriers to entry: Starting in the 1970’s since there were no trade barriers companies overseas were able to manufacture and sell steel for a much lower price here in the United States therefore affecting companies domestically. Supplier power: Once steel became

------------------------------------------------- Alloy Steel is a metal alloy whose major component is iron‚ with carbon content between 0.02% and 2.14% by mass. An alloy is a metallic solid solution composed of two or more elements. Complete solid solution alloys give single solid phase microstructure‚ while partial solutions give two or more phases that may or may not be homogeneous in distribution‚ depending on thermal (heat treatment) history. Alloys usually have different properties from those

Steel and heat treatment MILD STEEL Mild steel is also called plain carbon steel. It is the most common type of steel and it price is pretty low. Its composition is around about 0.05%-0.29% carbon content. Mild steel has a relatively low tensile strength but the surface can be hardened through carburizing. It is mostly used where large amounts of steel needs to be formed eg structural steel MEDIUM CARBON STEEL Medium carbon steel has great wear resistance and is used for forged automotive

discovered. This microstructure was named by Bian’s colleageus at the United States Steel Corportion. At first microstructure of martensite and bainite seem similar‚ which had many aspects on their transformation of mechanisms. Microstructure of bainite seems to be darker than the mastenisite under a microscope. The reason behind bainite structure became useful was because of its hardness. There are few Heat treatments that steel can be tested by such as Annealing‚ quenching Harderning‚ and Normalizing.
