Harsh Metalloys, a reputable manufacturer and supplier based in Mumbai, India, specializes in top-notch Stainless Steel 384 Bolts, celebrated for their outstanding corrosion resistance and remarkable formability. SS 384 is an austenitic stainless steel alloy that boasts higher levels of Nickel and Chromium compared to 304, making it a go-to choice for challenging environments rich in corrosive elements and chlorides. These bolts are crafted to comply with ASTM, DIN, and various international standards, guaranteeing precise dimensions, durability, and a long lifespan. SS 384 bolts are perfect for use in marine, chemical processing, food and beverage, and pharmaceutical sectors where hygiene and corrosion resistance are paramount.
Stainless Steel 384 Bolts are made up of roughly 18–20% Chromium and 26–30% Nickel, with a low Carbon content (≤ 0.08%) that boosts corrosion resistance and helps avoid carbide precipitation during welding. This unique composition provides excellent protection against pitting, stress corrosion cracking, and intergranular corrosion. SS 384 bolts exhibit a tensile strength of about 520–620 MPa and maintain impressive ductility and toughness, even in cryogenic conditions. They are non-magnetic when annealed and can be easily cold-worked or machined, making them ideal for corrosive, high-moisture, and sanitary environments.
