Stainless Steel 440C Square Bars and Rods are high-carbon martensitic stainless steel alloys known for their excellent hardness and wear resistance. Composition typically includes 16-18% chromium, 0.95-1.20% carbon, and small amounts of manganese, silicon, and nickel. Mechanical properties include high tensile strength (up to 205 ksi), excellent hardness (58-60 HRC), and good corrosion resistance. This kind of material resists wear amazingly and is considered for applications which involve high pressure like bearings, valves, or cutting tools. Exceptional hardness with resistance to corrosion, wear and heat is maintained with this.

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.
Stainless Steel 440C Square Bars and Rods are applied in a lot of industries which require high strength, wear resistance, and corrosion resistance. Their applications are generally in bearings, valve components, pump shafts, and tooling because they have excellent hardness and resistance to corrosion and oxidation. They are also used in the manufacture of surgical instruments, knives, and cutlery. Their resistance to high temperatures makes them versatile for use in extreme conditions such as chemical processing and marine applications. They are further used in aerospace, automotive, and industrial machinery components for high-performance duration.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
