Product Description
403 Stainless Steel
403 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard. 403 stainless steel is a stainless heat-resistant steel developed for the production of steam turbine blades and high-stress components. It is composed of carbon, manganese, chromium, nickel and other chemicals. It has high tensile strength and is generally delivered in a heat-treated state. It can has esistance and a scaling temperature of about 1300°F. It is a corrosion and heat resistant 12% Cr martensitic stainless steel. This alloy offers a wide range of mechanical properties that are obtainable by appropriate heat treatments. It is easily hardened by oil, fan or air cooling and may be tempered at temperatures of up to 1350°F (732°C) to improve fracture toughness. Oil or fan cooling is required in thicker sections
400 Series - Ferritic and Martensitic Stainless Steels
408—Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
409 - The cheapest model (British and American), usually used as a car exhaust pipe, is a ferritic stainless steel (chromium steel).
410—Martensitic (high-strength chromium steel), with good wear resistance and poor corrosion resistance.
416 - The addition of sulfur improves the processing properties of the material.
420 - "cutting grade" martensitic steel, the earliest stainless steel similar to Brinell high chromium steel. Also used in surgical knives, can do very bright.
430—ferritic stainless steel, used for decoration, such as for car accessories. Good formability, but poor temperature and corrosion resistance.
440—High-strength cutting tool steel, with slightly higher carbon content, high yield strength can be obtained after proper heat treatment, and the hardness can reach 58HRC, which is one of the hardest stainless steels. The most common application example is "razor blades". There are three commonly used models: 440A, 440B, 440C, and 440F (easy to process).
