Yes, Stainless Steel 440C Square Bars are magnetic. This is because they are martensitic stainless steel, which contains a high amount of carbon, making them ferromagnetic.
Yes, Stainless Steel 440C square rods can be heat-treated to improve hardness and strength. The typical heat treatment process includes austenitizing, quenching, and tempering.
Stainless Steel 440C square bars offer excellent high-temperature strength and maintain their hardness and wear resistance in elevated temperatures. However, prolonged exposure may lead to some reduction in toughness and ductility.
These Stainless Steel 440C Square Bars and Rods are commonly used in fields that require high hardness, strength, and wear resistance. Industries such as aerospace, automotive, tool manufacturing, and mechanical engineering frequently utilize these bars. They are ideal for producing ball bearings, valve components, surgical instruments, knives, and molds. Their ability to maintain sharp edges and resist deformation under load makes them perfect for precision instruments and cutting tools. Additionally, 440C rods find applications in marine environments and pump shafts, where both corrosion and abrasion resistance are essential for long-lasting performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
