420 stainless steel is a kind of martensitic stainless steel, which has the characteristics of certain wear resistance and corrosion resistance, and high hardness. 420 stainless steel is a martensitic grade of stainless steel that contains chromium and molybdenum, making it corrosion-resistant and hardenable. It has good strength, hardness, and wear resistance, and is commonly used in applications where high strength and moderate corrosion resistance are required, such as in cutlery, surgical instruments, and dental equipment. Some of the key properties of 420 stainless steel include: Corrosion resistance: 420 has good corrosion resistance in mild atmospheric environments and in most mild chemical environments. Hardness: 420 is a hardenable stainless steel and can be hardened by heat treatment, making it ideal for applications where high hardness is required. Wear resistance: 420 has good wear resistance due to its high hardness. Machinability: 420 has moderate machinability in the annealed condition, but is more difficult to machine in the hardened condition. Some of the common applications for 420 stainless steel include: Cutlery, including knives, scissors, and blades Surgical instruments, such as scalpels and forceps Dental equipment, including dental drills and hand tools Valve parts Pump shafts and bearings Overall, 420 stainless steel is a reliable and versatile material that is well-suited for use in applications where high strength, hardness, and moderate corrosion resistance are required. Here are some of the most common international standards for 420 stainless steel: ASTM A276: Standard Specification for Stainless Steel Bars and Shapes ASTM A314: Standard Specification for Stainless Steel Billets and Bars for Forging ASTM A473: Standard Specification for Stainless Steel Forgings ASTM A580: Standard Specification for Stainless Steel Wire EN 10088-3: Stainless steels - Part 3: Technical delivery conditions for semi-finished products, bars, rods, wire, sections and bright products of corrosion resisting steels for general purposes JIS G4303: Stainless steel bars GB/T 1220: Stainless steel bars We can provide the following form:420 stainless steel coil; 420 stainless stee strip;420 stainless stee plate; 420 stainless steel sheets; 420 stainless steel tubes; 420 stainless steel pipe; 420 stainless steel flat; 420 stainless steel bar 420 stainless steel is suitable for all kinds of precision machinery, bearings, electrical appliances, equipment, instruments, meters, transportation tools, household appliances, etc. It is mostly used in the manufacture of parts resistant to atmosphere, water vapor, water and oxidative acid corrosion.
