Grade 1.4529 is a high alloy stainless steel of austenitic structure and can be classified as a nickel alloy (by US standards). Delivered in a supersaturated condition, it exhibits resistance to intergranular corrosion, pitting and stress corrosion, salt, seawater, chlorides, sulfuric acid, phosphoric acid, and other highly concentrated liquid and gaseous corrosive chemicals. At the same time, nickel and nitrogen can not only improve the stability, but also reduce the tendency of separation of crystallization thermal process or welding process is better than the nitrogen content of nickel alloy. 926 has some corrosion resistance to chloride ions due to its localized corrosion characteristics and 25% nickel alloy content.
