Walid Stainless, based in Tunis, Tunisia, is a reliable manufacturer and supplier of stainless steel 440C sheets and plates for applications demanding exceptional hardness, strength, and wear resistance. Produced using advanced rolling and heat-control processes, these sheets and plates offer uniform thickness, smooth surface finish, and consistent quality. Stainless steel 440C is a high-carbon martensitic grade known for achieving very high hardness through heat treatment. Walid Stainless supplies industries such as tooling, bearings, automotive, aerospace, and precision engineering, delivering durable materials supported by technical expertise and customer-focused service.
Stainless steel 440C is a high-carbon martensitic stainless steel alloyed with chromium to provide corrosion resistance and superior hardness. Its composition allows it to reach very high hardness levels after proper heat treatment, resulting in excellent wear resistance and strength. The material offers high tensile strength, good edge retention, and reliable load-bearing capacity. Although its corrosion resistance is lower than austenitic grades, stainless steel 440C performs well in mild to moderately corrosive environments and maintains dimensional stability under mechanical stress.
