Rupal Metals stands out as a top manufacturer and supplier of Stainless Steel 440C Hex Bars, proudly based in Delhi, India. They specialize in crafting precision-engineered hexagonal bars that are perfect for high-performance and wear-resistant applications. Known for its high-carbon martensitic properties, Stainless Steel 440C boasts impressive hardness, strength, and moderate corrosion resistance. These hex bars are ideal for industries that prioritize dimensional accuracy and durability, and Rupal Metals offers them in a variety of sizes and finishes. You’ll find these bars commonly used in making tools, dies, and mechanical parts that demand exceptional wear resistance, polishability, and reliable performance under pressure.
Stainless Steel 440C Hex Bars generally consist of Carbon (0.95–1.20%), Chromium (16–18%), Manganese (≤1%), Silicon (≤1%), and small amounts of Molybdenum. This unique blend allows the steel to reach impressive hardness levels—up to 60 HRC after heat treatment. With a tensile strength ranging from 760–965 MPa, it offers excellent wear resistance and solid dimensional stability. While it may not resist corrosion as well as austenitic grades, it performs effectively in dry or mildly corrosive settings. 440C combines high mechanical strength with great edge retention and machinability, making it a go-to choice for high-precision industrial applications.

Heat treatment of SS 440C involves hardening by quenching and tempering, significantly increasing hardness and wear resistance. Proper heat treatment also enhances corrosion resistance, making the material suitable for demanding applications.
SS 440C Hex Bar is commonly used in bearings, shafts, valves, and tools. Its high hardness, wear resistance, and moderate corrosion resistance make it preferred over other stainless steels for demanding, high-strength applications.
Stainless Steel 440C Hex Bars find their place in industries that need components with exceptional hardness, abrasion resistance, and precise machining capabilities. They’re commonly used in the production of surgical instruments, valves, bearings, nozzles, pump shafts, dies, and industrial blades. The hexagonal shape enhances grip and strength during fastening or machining, making it perfect for custom parts in aerospace, defense, tooling, and mechanical systems. Its outstanding polishability and ability to maintain a sharp edge make it a favorite for cutlery and high-end tools. 440C hex bars excel in moderately corrosive environments where hardness is key.
