Harsh Metalloys, Mumbai, India, is a renowned manufacturer and exporter of Stainless Steel 440 Bars, appreciated for their high hardness, wear resistance, and corrosion resistance. Produced from high-carbon martensitic stainless steel, these bars provide superior mechanical properties needed for high-performance industrial usage. Harsh Metalloys offers precision-crafted 440 bars in several dimensions and finishes according to client requirements. Our stainless steel bars find extensive application in industries like aerospace, automobile, tooling, and defense, providing durability, strength, and long-term performance in hostile environments.
Stainless Steel 440 Bars contain mostly 16–18% chromium and 0.95–1.2% carbon, with a martensitic structure that confers high hardness (60 HRC) and tensile strength up to 760 MPa after heat treatment. These bars have superior wear resistance and average corrosion resistance, ideal for conditions subjected to mechanical loads and mild corrosive substances. Their high carbon proportion improves strength and size stability, which is ideal in precision parts. Harsh Metalloys assures rigorous quality control for assured strength, hardness, and surface finish in all the bars supplied.
