Stainless Steel Bolt

  Stainless steel refers to a family of iron-based alloys that must include at least 10.5% chromium and may also contain nickel, manganese, molybdenum, sulphur, selenium, titanium, and other alloying elements. Table 2 may be found on page 3. The chromium is primarily responsible for the corrosion and heat resistance of stainless steel; the other alloying elements are present in stainless steel to further enhance the material's resistance to corrosion as well as to impart certain characteristics regarding the material's strength and its ability to be fabricated. The American Iron and Steel Institute (AISI) first acknowledged as standard compositions a total of sixty different commercial varieties of stainless steel. Design Guidelines for the Selection and Use of Stainless Steel is a document by SSINA that contains a comprehensive inventory of all stainless steels as well as a description of each. The United States and Canada are responsible for the production of a wide variety o
