Poang Fasteners is a reliable manufacturer and supplier of Stainless Steel 316 Washers based in Da Nang, Vietnam. We specialize in providing fastening solutions that are built to withstand corrosion and last over time. SS 316 is an austenitic stainless steel alloy enriched with molybdenum, which gives it remarkable resistance to chlorides, pitting, and crevice corrosion. Our SS 316 Washers are crafted to meet ASTM, DIN, and ISO standards, ensuring they are accurate, strong, and perform consistently. These washers find extensive use in marine, petrochemical, pharmaceutical, and food processing industries, where durability and resistance to harsh conditions are essential.
Stainless Steel 316 Washers are made up of 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, along with trace amounts of manganese, silicon, phosphorus, and a maximum of 0.08% carbon. The addition of molybdenum significantly boosts their resistance to environments rich in chlorides and acids, making them superior to SS 304. They offer a tensile strength ranging from 515 to 620 MPa, a yield strength of about 205 MPa, and maintain excellent toughness even in freezing temperatures. In their annealed state, SS 316 Washers are non-magnetic and boast great weldability and formability. These characteristics make them incredibly durable, corrosion-resistant, and reliable for critical fastening needs in demanding industries.
