Stainless Steel 384 Nuts are crafted from an austenitic stainless steel alloy that boasts high levels of Chromium (18-20%), Nickel (26-32%), and Manganese (2%). This unique blend significantly boosts corrosion resistance, particularly in oxidizing environments. SS 384 is known for its remarkable toughness and strength, even under high temperatures. The mechanical properties include a minimum tensile strength of 550 MPa, yield strength of 240 MPa, and an elongation of 35% in 50mm. With a density of 8.0 g/cm³, it remains stable up to 870°C intermittently, making SS 384 Nuts perfect for demanding mechanical and structural applications.
