ASTM/ASME 440A Stainless Steel Pipes & Tubes are high-carbon martensitic (UNS S44002) products conforming to ASTM A213/A268 standards, featuring a precision-balanced chromium (16-18%) and carbon (0.60-0.75%) composition for exceptional hardness (up to 58 HRC when heat-treated) and wear resistance. This premium cutlery-grade alloy offers superior edge retention and moderate corrosion resistance compared to 420 series, with optimized tempering stability for applications requiring extreme durability. The material achieves its maximum performance through controlled quenching and tempering processes, developing high compressive strength while maintaining better corrosion resistance than 440B/C variants. Primarily used in specialized industrial blades, surgical tools, and bearing components, 440A stainless steel tubes serve critical roles in food processing equipment, precision instruments, and mechanical systems where ultra-high hardness must be balanced with stain resistance, though requiring expert heat treatment and having limited weldability characteristic of high-carbon martensitic grades.
