Weston Stainless of Midland, UK, is a reliable stainless steel manufacturer and supplier of premium-quality stainless steel products, including industrial-grade precision-coiled stainless steel. Some of their best products include Stainless Steel 440C Coils, which stand out for their superior hardness, wear resistance, and corrosion resistance. These coils are produced from Grade 440C stainless steel and come in various shapes, such as slit, annealed, and cold-rolled form. The alloy, a high-carbon martensitic stainless steel, offers excellent strength and toughness, making it perfect for uses where superior mechanical properties and excellent wear resistance in harsh environments are necessary.
Stainless Steel 440C Coils contain a chemical composition of about 16-18% Chromium, 0.95-1.20% Carbon, 0.75% Molybdenum, and trace amounts of Silicon, Manganese, and Nickel, which improve their hardness and resistance to corrosion. These coils have very good mechanical properties such as tensile strength of approximately 760-1970 MPa, yield strength of 450 MPa, and up to 60 HRC hardness upon heat treatment. In terms of physical properties, they possess high density, thermal conductivity, and oxidation resistance, which renders them suitable for high-stress applications where very high hardness and durability are needed.

Exceptional hardness and strength, making them perfect for precision-cutting tools and high-stress applications. Their durability and wear resistance enhance performance in demanding environments.
Excellent hardness and wear resistance, ideal for precision applications. Their durability and corrosion resistance make them suitable for high-stress components like cutting tools and bearings.
High hardness and wear resistance. They are ideal for precision components such as cutting tools and bearings, offering durability and reliable performance.
Stainless Steel 440C Coils have a broad industrial application in fields like aerospace, automotive, and medical because they possess superior wear resistance and strength. They can be used broadly in the fabrication of surgical devices, bearings, cutlery, valves, and high-performance components that get exposed to rigorous wear conditions. The coils find application in pump shafts, rolling elements, and tools too that need optimum hardness and anti-corrosive properties. Their capacity to uphold structural integrity at high temperature and pressure renders them critical in heavy-duty industrial equipment and special engineering applications.
Stainless Steel 440C Coils are accompanied by test certificates like Mill Test Certificates (MTC) as per EN 10204 3.1/3.2, third-party inspection reports, and material traceability records. They are packed safely in wooden crates, pallets, or wrapped in protective plastic to safeguard against transit damage. Easy identification is facilitated through proper labeling, and deliveries are streamlined to cater to international demands so that standards are met and shipment is made on time to clients across the globe.
