The exceptional strength of Duplex Steel Bolts comes from a unique composition that blends chromium, nickel, molybdenum, and nitrogen. This gives them a remarkable blend of high tensile strength and outstanding resistance to corrosion, particularly against stress corrosion cracking. They essentially combine the best attributes of austenitic and ferritic steels, resulting in a fastener that is significantly stronger than standard stainless steel options while maintaining excellent toughness and durability under pressure, making them ideal for heavy-load situations.
