Chanchai Stainless offers Stainless Steel 446 Bolts in Bangkok, Thailand. These bolts are engineered for strong resistance to oxidation and corrosion in high-temperature environments. As a ferritic stainless steel with high chromium content, grade 446 is known for its excellent scaling resistance at temperatures up to 1100°C. These bolts offer cost-effective fastening solutions in industrial applications exposed to extreme heat, sulfuric gases, and oxidizing conditions. With good creep strength and toughness, Stainless Steel 446 Bolts are reliable choices for parts in furnaces, chemical processing equipment, and power plant applications. Chanchai Stainless ensures consistent quality and durability for demanding environments.
Stainless Steel 446 bolts contain chromium (23-27%), molybdenum (0.5-1.5%), and very low carbon (<0.20%). The high chromium content provides outstanding scaling and oxidation resistance at elevated temperatures. Mechanical properties include a tensile strength of around 485 MPa and a yield strength of about 275 MPa, with moderate elongation. The ferritic structure ensures stability during thermal cycling and resistance to sulfidation. While not as strong as austenitic grades, Stainless Steel 446 delivers excellent high-temperature corrosion resistance, making it suitable for harsh heat and chemical environments.
