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.
You’ll find Stainless Steel 440C Hex Bars commonly used in situations that require high hardness, wear resistance, and moderate corrosion protection. They’re perfect for crafting bearings, valve parts, surgical instruments, pump shafts, cutting tools, and measuring devices. In industries like aerospace, marine, defense, and industrial manufacturing, these bars perform exceptionally well where strength and longevity are crucial. Their hexagonal shape not only enhances grip and fitment in mechanical assemblies but also, thanks to the steel’s ability to be hardened and precision-machined, makes it a favored choice for demanding structural and engineered components.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
