Stainless Steel 314 Nuts consist mainly of 24–26% chromium, 19–22% nickel, and a small content of manganese, silicon, carbon, and iron. It is high-alloy austenitic stainless steel with excellent resistance to oxidation and high-temperature corrosion. These nuts generally possess a tensile strength of about 600 MPa, yield strength of approximately 310 MPa, and very good ductility with an elongation of up to 40%. Their Brinell hardness varies between 150 to 200. Owing to their stable mechanical properties even at high temperatures, Stainless Steel 314 Nuts are particularly suitable for applications under high stress and high temperatures, promoting both strength and durability.
