  1. Stainless steel By: Keyonna L. Deshunte’ Benham Stefon Sampson NadimAntar Wilde

  2. Stainless steel is an iron-containing alloy—a substance made up of two or more chemical elements—used in a wide range of applications. It has excellent resistance to stain or rust due to its chromium content, usually from 12 to 20 percent of the alloy. Background

  3. Stainless steels are made of some of the basic elements found in the earth: iron ore, chromium, silicon, nickel, carbon, nitrogen, and manganese. Properties of the final alloy are tailored by varying the amounts of these elements. Nitrogen, for instance, improves tensile properties like ductility. It also improves corrosion resistance, which makes it valuable for use in duplex stainless steels. Raw Materials

  4. Process of Stainless Steel

  5. Steel Shapes

  6. In addition to in-process control during manufacture and fabrication, stainless steels must meet specifications developed by the American Society for Testing and Materials (ASTM) with regard to mechanical properties such as toughness and corrosion resistance. Metallography can sometimes be correlated to corrosion tests to help monitor quality. Quality Control

  7. Use of stainless and super stainless steels is expanding in a variety of markets. To meet the requirements of the new Clean Air Act, coal-fired power plants are installing stainless steel stack liners. Other new industrial applications include secondary heat exchangers for high-efficiency home furnaces, service-water piping in nuclear power plants, ballast tanks and fire-suppression systems for offshore drilling platforms, flexible pipe for oil and gas distribution systems, and heliostats for solar-energy plants. Future Of Stainless Steel

  8. Why is stainless steel so stainless? • What is an alloy? • What is stainless steel mostly made of? • What are the shapes of bars that stainless steel is made into? Questions

  9. It is stainless due to its chromium content. • An alloy is a substance made up of two or more chemical elements. • Iron • Blooms, bullets, and Slabs
