Harsh Metalloys, based in Mumbai, India, stands out as a top manufacturer and supplier of high-performance Stainless Steel 304L Bolts. These bolts are highly regarded for their impressive corrosion resistance, strength, and weldability. Crafted from low-carbon 304L stainless steel, they offer superior protection against intergranular corrosion after welding, making them perfect for structural and high-pressure applications. At Harsh Metalloys, we follow global standards like ASTM, DIN, and ASME to create precision-engineered bolts suitable for industrial, commercial, and marine uses. With a strong commitment to quality and customer satisfaction, we provide reliable fastening solutions to clients both in India and around the world.
Stainless Steel 304L Bolts boast a chemical makeup that includes Chromium (18–20%), Nickel (8–12%), Carbon (≤0.03%), Manganese (≤2%), Silicon (≤1%), Phosphorus (≤0.045%), and Sulfur (≤0.03%). These bolts are celebrated for their outstanding corrosion resistance and weldability, particularly in chloride or acidic settings. Their mechanical properties feature a tensile strength of at least 485 MPa, yield strength of at least 170 MPa, elongation of at least 40%, and a hardness of no more than 92 HRB. The low carbon content helps prevent carbide precipitation during welding, ensuring the bolts maintain their integrity and durability in critical applications.
