ASTM ASME 420J2 Stainless Steel Pipes & Tubes

ASTM/ASME 420J2 Stainless Steel Pipes & Tubes are high-carbon martensitic (UNS S42020) products conforming to ASTM A213/A268 standards, featuring optimized chromium (12-14%) and carbon (0.26-0.40%) content for maximum hardness (up to 54 HRC when heat-treated) and cutting-edge retention. This premium cutlery-grade alloy offers enhanced wear resistance and moderate corrosion protection compared to standard 420 stainless, making it particularly suitable for precision blades, surgical instruments, and industrial cutting tools requiring durable sharp edges. The material achieves its exceptional mechanical properties through precise heat treatment processes, with improved polishability and stain resistance over 420J1 grade. While primarily utilized in specialized applications rather than structural piping, 420J2 stainless steel tubes serve critical roles in food processing machinery, pharmaceutical equipment, and precision engineering components where extreme hardness must be balanced with moderate corrosion resistance, though requiring post-weld heat treatment to maintain performance characteristics.
