Stainless Steel 316L Bolts are top-notch, corrosion-resistant fasteners crafted for tough and chemically aggressive environments. Being a low-carbon version of the 316 stainless steel grade, these bolts excel in resisting pitting, crevice corrosion, and chloride-induced damage, making them perfect for marine, chemical, and industrial uses. Their low carbon content not only enhances weldability but also prevents carbide precipitation during welding or fabrication. With Stainless Steel 316L Bolts, you can count on reliable performance, durability, and a long service life, even in conditions where moisture, chemicals, and high temperatures are the norm.
These bolts are made up of chromium (16–18%), nickel (10–14%), molybdenum (2–3%), and low carbon levels that boost both corrosion resistance and weldability. They typically deliver a tensile strength of 485–620 MPa and a yield strength of about 170–240 MPa, along with impressive ductility and elongation. The inclusion of molybdenum greatly enhances resistance to pitting and crevice corrosion, particularly in environments rich in chloride. Their consistent mechanical properties across different temperatures make SS 316L Bolts a great fit for demanding and corrosive applications.
