Stainless Steel Grade 440C | UNS# S44004 is a high carbon martensitic stainless steel that demonstrates high strength, moderate corrosion resistance, and good hardness and wear resistance. The highest resistances for type 440C can be achieved by hardening and polishing which make this material ideal for cutting instrumentation, surgical blades, and knife blades. Because of these traits it is also common to find type 440C in ball bearings, valves, and measuring instruments.
