403 stainless steel pipe is a brand of stainless steel produced according to the American ASTM standard 403 is equivalent to 1Cr12 stainless steel pipe, containing 0.01% carbon and 12% chromium 403 stainless steel pipes belong to the international stainless steel labeling method. 403 stainless steel pipe--S40300 (American AISI, ASTM) 403 corresponds to the Chinese grade is 1Cr12 403 stainless steel is a martensitic stainless steel that contains chromium, which provides it with excellent corrosion resistance properties. It is a heat-treatable alloy that can be hardened to achieve high strength and hardness levels. However, its corrosion resistance is lower compared to other stainless steel grades such as 304 and 316. Some of the key properties of 403 stainless steel include: Corrosion resistance: 403 stainless steel offers good corrosion resistance in mild environments, but its corrosion resistance is not as good as other austenitic stainless steel grades. Heat resistance: 403 stainless steel has good heat resistance and can be used at temperatures up to 649�°C (1200�°F). Hardness and strength: 403 can be heat treated to achieve high levels of hardness and strength. Machinability: 403 has good machinability in the annealed condition, but it can be difficult to machine in its hardened state. Some of the common applications for 403 stainless steel include: Pump shafts Valve parts Cutlery Surgical instruments Machine parts Overall, 403 stainless steel is a heat-treatable alloy that offers good corrosion resistance in mild environments and is well-suited for applications that require high strength and hardness. However, it is not recommended for use in corrosive environments or applications that require high resistance to pitting and crevice corrosion. Here are some of the most common international standards for 403 stainless steel: ASTM A240/A240M: Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications. ASTM A276: Standard Specification for Stainless Steel Bars and Shapes. ASTM A479/A479M: Standard Specification for Stainless Steel Bars and Shapes for Use in Boilers and Other Pressure Vessels. EN 10088-2: Stainless steels - Part 2: Technical delivery conditions for sheet/plate and strip of corrosion resisting steels for general purposes. JIS G4304: Hot-rolled stainless steel plate, sheet and strip. GB/T 3280: Cold rolled stainless steel plate, sheet and strip.
