Stainless Steel 384 consists of 18-20% chromium, 10-13% nickel, and trace amounts of manganese and nitrogen. It provides tensile strength between 500-750 MPa and yield strength of about 200 MPa. SS 384 offers excellent ductility, good workability, and strong corrosion resistance, particularly in chloride and acidic settings. It is non-magnetic in the annealed state and remains stable under varying temperatures. These characteristics make SS 384 nuts particularly effective in environments that demand long-term performance without compromising formability or resistance.
