Our Duplex Steel Screws are crafted from a unique composition of chromium, nickel, molybdenum, and nitrogen. This specific blend gives them an outstanding combination of high strength and exceptional resistance to corrosion, particularly against stress corrosion cracking. They effectively bridge the gap between austenitic and ferritic steels, offering a yield strength that is roughly double that of standard stainless steels, making them incredibly durable and dependable under heavy loads.
