Product Description
400 series stainless steel is an iron, carbon and chromium alloy. This stainless steel has a martensitic structure and an iron element and therefore has normal magnetic properties. 400 series stainless steel has a strong resistance to high-temperature oxidation and compared with carbon steel, its physical properties and mechanical properties have been further improved. Most 400 series stainless steel can be heat treated.
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 stainless steel bar: belongs to 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 stainless steel bar: "cutting grade" martensitic steel, the earliest stainless steel similar to Brinell high chromium steel. Also used in surgical knives, can do very bright.
430 stainless steel bar: 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 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 processing type).
