Stainless steel 440C is known for its high carbon content and ability to achieve high hardness through heat treatment. Walid Stainless serves industries such as bearing manufacturing, tooling, automotive, and precision engineering, delivering materials that combine strength, durability, and consistent quality with responsive customer support.
Stainless steel 440C is a high-carbon martensitic stainless steel containing significant chromium content for corrosion resistance and hardness. Its composition allows it to achieve very high hardness and excellent wear resistance after proper heat treatment. The material offers high tensile strength, good edge retention, and strong load-bearing capability. While its corrosion resistance is lower than austenitic grades, it performs well in mildly corrosive environments. Stainless steel 440C coils maintain dimensional stability and mechanical strength under demanding mechanical stress conditions.
