Poang Fasteners is a reliable manufacturer and supplier of Stainless Steel 446 Fasteners based in Da Nang, Vietnam. We provide high-performance fastening solutions designed for extreme service conditions. Stainless Steel 446 is a ferritic stainless steel known for its impressive chromium content, which gives it outstanding resistance to oxidation, sulfidation, and scaling at high temperatures. Our SS 446 Fasteners come in various forms, including bolts, nuts, washers, screws, stud bolts, and threaded rods, all produced according to ASTM, DIN, and ISO standards. These fasteners are widely utilized in power generation, petrochemical, furnace equipment, cement, and heat-treatment industries where strength and thermal stability are crucial.
Stainless Steel 446 Fasteners mainly consist of 23–27% chromium, with very low carbon content (<0.20%) and small amounts of manganese, silicon, phosphorus, and sulfur. This ferritic alloy can’t be hardened through heat treatment, but it offers remarkable resistance to oxidation and scaling at temperatures up to about 1100°C (2010°F). The mechanical properties include a tensile strength of around 485 MPa and a yield strength of approximately 275 MPa, along with excellent resistance to creep and thermal fatigue. These fasteners maintain their dimensional stability, toughness, and durability even when exposed to high heat for extended periods, making them a dependable choice for severe high-temperature applications.
