We provide a large selection of industrial-grade materials that are suited to demanding applications, with a strong emphasis on quality, innovation, and customer satisfaction. Stainless Steel 440B Sheets and Plates, which are renowned for their high hardness, exceptional wear resistance, and moderate corrosion resistance, are among our superior products. Our 440B sheets and plates are made to international standards, making them appropriate for both domestic and international markets. They are perfect for high-strength and precision components.
High-carbon martensitic stainless steel 440B has 0.75–0.95% carbon and roughly 16–18% chromium. After the right heat treatment, this composition gives the material good corrosion resistance, high hardness, and excellent wear resistance. Its mechanical characteristics include a yield strength of approximately 450 MPa and a tensile strength of 740–860 MPa. It can reach hardness levels of up to 58 HRC after heat treatment. 440B is perfect for precision applications needing long-lasting performance because of its well-balanced strength, hardness, and moderate corrosion resistance.
