Weston Stainless in Midland, UK, is a world-class producer and distributor of premium stainless steel products that provide precision-engineered industrial solutions. Of their high-end products, Stainless Steel 440B Sheet and Plates are much acclaimed for their high hardness, wear resistance, and corrosion resistance. Produced using Grade 440B stainless steel, these sheets and plates are provided in multiple shapes such as flat, rectangular, and bespoke sizes. The material, a martensitic stainless steel with high carbon content, exhibits superior mechanical strength and durability and is best suited for applications involving high performance and high resistance to severe wear and corrosion.
Stainless Steel 440B Plates and Sheets contain about 16-18% Chromium, 0.75-1.00% Carbon, and trace amounts of Manganese, Silicon, and Phosphorus. The composition gives the material increased corrosion resistance and mechanical properties. These sheets and plates possess remarkable mechanical strength with tensile strength of 760-1970 MPa, yield strength of around 450 MPa, and hardness up to 58 HRC when heat-treated. Their physical characteristics are high density, good thermal conductivity, and excellent oxidation resistance, qualifying them for high-stress and high-temperature uses.
