Nitronic 30 (UNS S20400) is a nitrogen-strengthened stainless steel alloy which was initially developed to offer superior corrosion resistance in aqueous and atmospheric atmospheres.
It is known as abrasion-resistant steel and is still used today in high wear applications such as coal buckets, hoppers and magnetic ore separator screens. Combined with good overall toughness, the alloy provides an economical solution in a broad range of applications. Nitronic 30 offers numerous benefits - the material is significantly stronger than 304 stainless steel (up to 50% higher yield).
Alloy applications include fasteners, hose clamps, bumpers and structural framework. The material is easily welded and will withstand substantial impact without cracking. The strength to weight ratio alone is up to three times greater than carbon steel.
Nitronic 30 is available in round bar and plate.
Good machinability using conventional machining techniques when using resulphurised lubricant at slow speeds.
Equivalents include ASTM A240 and ASTM A666
