Garg Steels, a reputable manufacturer and supplier located in Chennai, India, specializes in top-notch Stainless Steel 440C Bars and Rods designed for high-performance industrial applications. Renowned for their remarkable hardness, wear resistance, and strength, 440C is a high-carbon martensitic stainless steel grade that excels in demanding mechanical environments. Garg Steels guarantees precision in manufacturing, dimensional accuracy, and compliance with international standards, making their products perfect for critical operations. These bars and rods find extensive use in industries like toolmaking, aerospace, automotive, and medical, where high strength, edge retention, and corrosion resistance are essential for optimal performance and durability.
Stainless Steel 440C Bars and Rods consist of about 16–18% chromium, 0.95–1.20% carbon, along with trace amounts of manganese, silicon, and molybdenum. This martensitic stainless steel achieves a high hardness range (up to 60 HRC) when heat-treated, offering excellent wear resistance and moderate corrosion resistance. It boasts a tensile strength of approximately 760–950 MPa and good dimensional stability. 440C is well-suited for high-stress applications that require strength, hardness, and edge retention, although its corrosion resistance is somewhat lower than that of austenitic stainless steels, particularly in marine or acidic environments.
