Chanchai Stainless provides Stainless Steel 442 Bolts in Bangkok, Thailand. These bolts are engineered for excellent resistance to oxidation and scaling at high temperatures. As a ferritic stainless steel with high chromium content, grade 442 offers good corrosion resistance in mild environments and strong thermal stability. These bolts are made for industries needing fasteners that can handle high service temperatures without losing mechanical integrity. Stainless Steel 442 Bolts from Chanchai Stainless are cost-effective, durable, and produced to international standards, ensuring reliable performance and long service life in tough thermal and industrial applications.
Stainless Steel 442 bolts consist of chromium (18–23%), molybdenum (up to 0.6%), and low carbon (<0.20%). The ferritic structure offers high-temperature oxidation resistance up to 1095°C. The average tensile strength is 485 MPa, yield strength is about 275 MPa, and elongation is around 20%. While they are less ductile than austenitic grades, 442 provides reliable thermal stability and scaling resistance. Mechanical performance is sufficient for industrial fasteners exposed to heat and moderate corrosive conditions.
