Chanchai Stainless provides Stainless Steel 422 Bars in Bangkok, Thailand. These bars are designed for strength, wear resistance, and high-temperature performance. As a martensitic stainless steel, grade 422 is known for its mechanical strength and moderate corrosion resistance, making it suitable for applications exposed to heat and stress. These bars are used where toughness and thermal stability are important. Stainless Steel 422 Bars are heat treatable, offering improved hardness and creep resistance. Manufactured to international standards, Chanchai Stainless ensures quality and consistency, supplying 422 bars that perform reliably in industries needing strong fasteners and thermal components.
Stainless Steel 422 bars contain chromium (11–13%), molybdenum (0.5–1%), tungsten (~0.5%), vanadium (~0.25%), and carbon (~0.2%). Mechanical properties include tensile strength of 620–760 MPa, yield strength of 450 MPa, and hardness up to 45 HRC after heat treatment. They provide good creep resistance and toughness at high temperatures. Stainless Steel 422 delivers reliable performance in environments where mechanical strength and thermal durability are key.
