Poang Fasteners stands out as a top manufacturer and supplier of Stainless Steel 442 Fasteners in Da Nang, Vietnam. We pride ourselves on delivering high-quality fastening solutions designed for tough, high-temperature, and corrosive environments. Stainless Steel 442 is a ferritic stainless steel known for its exceptional resistance to oxidation and scaling, even at elevated temperatures. Our SS 442 Fasteners come in various forms, including bolts, nuts, washers, screws, stud bolts, and threaded rods, all crafted to meet ASTM, DIN, and ISO standards for precision and durability. These fasteners are widely utilized in heat treatment, furnace equipment, petrochemical, power generation, and marine applications, where reliability and thermal stability are crucial.
Stainless Steel 442 Fasteners are mainly made up of about 18% chromium and around 2% molybdenum, along with balanced amounts of carbon, manganese, and silicon. This unique blend boosts their resistance to oxidation and scaling, even at temperatures reaching approximately 1035°C (1900°F). With a tensile strength between 515–700 MPa and a yield strength of about 275 MPa, SS 442 is built for durability and toughness. Its ferritic microstructure provides excellent thermal fatigue resistance, creep strength, and stability under heat stress. These fasteners are designed to resist wear and offer a long service life, making them ideal for high-temperature industrial settings that demand mechanical integrity and resilience against aggressive thermal cycling.
