Stainless Steel 440C Hex Bars, a high-carbon martensitic stainless steel renowned for its remarkable strength, hardness, and resistance to wear, are supplied by George Metals, a reliable source. Our 440C hex bars, which are made for uses that call for heat treatable alloys, can be hardened at temperatures between 760°C and 1010°C (1400°F and 1850°F) and then quenched in air or oil. These bars provide a good mix of corrosion resistance and mechanical performance, making them perfect for high-stress components, shafts, and bearing applications. George Metals provides precisely engineered 440C hex bars that are ideal for industrial and marine settings where robustness is essential.
About 16–18% chromium, 0.95–1.20% carbon, 1.00% manganese, and 1.00% silicon are present in stainless steel 440C hex bars, along with trace amounts of phosphorus, sulfur, and other elements. The bars reach hardness levels of 58–60 HRC, yield strengths of 450–700 MPa, and tensile strengths of 1000–1200 MPa after heat treatment and tempering. Because of this, SS 440C is perfect for applications that require high wear resistance, impact strength, and moderate corrosion protection. These applications include bearings, valves, and cutting tools, among others, where accuracy and durability are crucial.

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.
Applications needing a combination of moderate corrosion protection and high wear resistance frequently use SS 440C Hex Bars. Shafts, valve components, pumps, cutting tools, and roller bearings are among the common applications, particularly in the automotive, aerospace, marine, and pharmaceutical manufacturing sectors. Additionally, gears, fasteners, pistons, and other high-stress parts that are subjected to impact or friction are perfect candidates for these bars. 440C hex bars are a solid option for demanding engineering applications because they can withstand a variety of conditions, including freshwater, mild acids, organic matter, and petroleum products, while still maintaining their hardness even after extended use.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
