Harsh Metalloys, a well-respected manufacturer and supplier located in Mumbai, India, specializes in top-notch Stainless Steel 416 Bolts that are perfect for applications needing high machinability and dependable mechanical performance. SS 416 is a martensitic, free-machining stainless steel celebrated for its impressive strength, wear resistance, and ease of machining. These bolts are crafted to meet international standards like ASTM A193, DIN, and ISO, ensuring they are precise and consistently high in quality. They are ideal for use in industrial machinery, automotive systems, and general engineering, providing a cost-effective fastening solution for components that require both high productivity and durability in mildly corrosive environments.
Stainless Steel 416 Bolts are made up of 12–14% Chromium and 0.15–0.30% Carbon, with added Sulfur (≥0.15%) to enhance machinability. These bolts can be heat treated to reach tensile strengths between 550–700 MPa and hardness levels up to 40 HRC. While they may not be as corrosion-resistant as austenitic grades, SS 416 offers adequate protection in dry or mildly corrosive settings. Its martensitic structure ensures excellent machinability, high strength, and wear resistance, making it a great choice for the high-volume production of precision bolts used in threaded assemblies and mechanical structures.
