Harsh Metalloys is a leading manufacturer and supplier of Stainless Steel 440C Coils in Mumbai, India, providing premium-grade materials for high-precision and heavy-duty industrial applications. Stainless Steel 440C is a high-carbon martensitic stainless steel renowned for its exceptional hardness, strength, and moderate corrosion resistance. These coils are ideal for applications requiring wear resistance and durability under high-stress conditions. Harsh Metalloys offers SS 440C coils in various thicknesses, widths, and finishes, catering to industries such as aerospace, medical, tooling, and automotive. Each product is manufactured under strict quality controls, conforming to international standards for performance and reliability.
Stainless Steel 440C Coils contain high carbon content (approximately 1.0%) and chromium (16–18%), which provide superior hardness (up to 60 HRC when heat-treated), excellent wear resistance, and moderate corrosion resistance in mild environments. The alloy displays high tensile strength (around 760–980 MPa) and excellent dimensional stability. SS 440C is magnetic and can be hardened through heat treatment for added strength. Harsh Metalloys ensures each coil features uniform thickness, smooth edges, and high surface quality, making it suitable for applications requiring machining, polishing, or further fabrication.
