Stainless Steel 442 Nuts consist mostly of chromium (18-23%), with smaller amounts of molybdenum, titanium, and carbon content, giving them higher levels of resistance to oxidation and scaling up to a temperature of 816°C (1500°F). The alloy possesses high tensile strength, satisfactory ductility, and toughness, with a normal tensile strength of 500–700 MPa and yield strength of approximately 250 MPa. These nuts are resistant to stability under harsh thermal and mechanical stress. Their corrosion resistance at atmospheric conditions and scaling at high temperatures makes them extremely suitable for use in structurally challenging and heat-intensive applications.
Stainless Steel 442 Nuts are widely applied in applications that require dependable fastening under high-temperature and corrosive conditions. Widely available in automotive exhaust systems, they are able to resist hot exhaust gases and inhibit fastener deterioration over time. They also find applications in power generation facilities, chemical reactors, furnace parts, and heat treatment units because they resist scaling and oxidation. Their strength of structure enables them to be appropriate for industrial equipment, chemical process apparatus, and boilers. They provide consistent, long-term performance under extreme conditions where safety, strength, and corrosion resistance are a concern.
