Harsh Metalloys is a leading manufacturer and supplier of Stainless Steel 420 Bolts based in Mumbai, India, providing premium-quality fastening solutions for a variety of industrial and mechanical applications. Stainless Steel 420 is a high-carbon martensitic stainless steel that offers excellent strength, hardness, and wear resistance. These bolts are specifically designed to perform under high-stress conditions where both mechanical strength and moderate corrosion resistance are essential. Available in various sizes, threads, and finishes, our SS 420 bolts are manufactured to meet international standards, making them suitable for use in engineering, automotive, aerospace, and general industrial applications.
Stainless Steel 420 Bolts typically contain 12–14% chromium with a high carbon content (0.15%–0.40%), which allows for heat treatment to attain hardness levels above 50 HRC. They provide excellent tensile strength, ranging from 700–850 MPa, and good fatigue and impact resistance. These bolts are magnetic and retain high mechanical performance after hardening. Harsh Metalloys ensures tight dimensional tolerances, strong threading, and consistent hardness across all products. The combination of wear resistance and moderate corrosion resistance makes 420 bolts a robust choice for heavy-load applications in varied environments.
