Poang Fasteners stands out as a top manufacturer and supplier of Stainless Steel 446 Stud Bolts in Da Nang, Vietnam. We provide top-notch fastening solutions for industries that face extreme heat and corrosion. SS 446 is a ferritic stainless steel known for its high chromium content, which gives it remarkable resistance to oxidation, scaling, and sulfidation, even at elevated temperatures. Our SS 446 Stud Bolts are crafted in line with ASTM, DIN, and ISO standards, ensuring they are both reliable and durable. These fasteners find their place in thermal power plants, furnaces, chemical processing units, and other high-temperature settings where outstanding heat and corrosion resistance is a must.
Stainless Steel 446 Stud Bolts are made up of 23–27% chromium, 0.20% carbon, and trace amounts of molybdenum, manganese, silicon, and nickel. This ferritic stainless steel is excellent at resisting scaling and oxidation at temperatures reaching up to 1100°C. SS 446 has a moderate tensile strength ranging from 485–620 MPa and maintains good dimensional stability during thermal cycling. Although it can’t be hardened through heat treatment, it excels in resisting sulfidation, hot gases, and corrosive environments. These characteristics make SS 446 Stud Bolts perfect for heavy-duty, high-temperature applications, ensuring long-lasting performance even in tough industrial conditions where standard fasteners might fail.
