Midland, UK-based Weston Stainless is a top supplier and producer of high-quality stainless steel products such as industrial–grade pipes. Of their superior quality products, Stainless Steel 440C Pipes are particularly famous for their superior hardness, corrosion resistance, and superior strength. Grade 440C stainless steel-based pipes are produced in different forms like seamless, welded, and ERW forms. The alloy, a high-carbon martensitic stainless steel, provides superior wear resistance and hardness, suitable for rigorous applications where better mechanical properties and high-performance characteristics are needed at very harsh conditions.
Stainless Steel 440C Pipes contain a chemical composition of about 16-18% Chromium, 0.95-1.20% Carbon, 0.75% Molybdenum, and minute traces of Silicon, Manganese, and Nickel, which increase their hardness as well as corrosion resistance. These pipes have very good mechanical properties in terms of tensile strength between 760 and 1970 MPa, yield strength approximately 450 MPa, and up to 60 HRC hardness after heat treatment. They have very good physical properties such as high density, good thermal conductivity, and very good oxidation resistance, which can accommodate high-temperature and high-stress environments.
