Weston Stainless, Midland, UK, is a reliable supplier and producer of quality stainless steel products that supply long-lasting solutions for a wide range of industrial uses. Among their high-end products, Stainless Steel 440C Sheet and Plates stand out in terms of their superior hardness, wear resistance, and corrosion resistance. These sheets and plates, produced from Grade 440C stainless steel, are offered in various shapes, such as hot-rolled, cold-rolled, and precision-cut. The material, high-carbon martensitic stainless steel, offers superior mechanical strength and durability and is ideal for use in applications that demand high performance, superior hardness, and resistance to harsh wear conditions.
Stainless Steel 440C Sheets and Plates contain a chemical composition of about 16-18% Chromium, 0.95-1.20% Carbon, 0.75% Molybdenum, and trace amounts of Manganese, Silicon, and Phosphorus, which improve their corrosion resistance and mechanical strength. These sheets and plates have remarkable mechanical behavior, such as tensile strength of 760-1970 MPa, yield strength of about 450 MPa, and hardness up to 60 HRC after heat treatment. The physical properties of the sheets and plates include high density, good thermal conductivity, and superior oxidation resistance, making them compatible with applications that need strength and stability at high-stress conditions.
