Stainless Steel 440C Coils, which are renowned for their remarkable hardness, wear resistance, and corrosion resistance, are among its most notable products. These coils, which have a high carbon and chromium content, are made for high-performance applications that require durability and dependability. Our 440C coils guarantee strength, durability, and efficiency under the most trying circumstances, whether they are used in precision components or industrial machinery. Vinit Stainless is your go-to source for premium stainless steel solutions, with an emphasis on innovation and client satisfaction.
With 1.1% carbon and 16–18% chromium, stainless steel 440C is a high-carbon martensitic grade that offers exceptionally high hardness (up to 60 HRC) and outstanding wear resistance following heat treatment. Additionally, it provides moderate to good corrosion resistance, especially in watery and mild chemical environments. Because the material retains its edge and sharpness, it can be used in repetitive mechanical movement and precision cutting applications. For industrial applications needing long-term performance and durability, its high tensile strength, dimensional stability, and galling resistance further increase its allure.
