 耐腐蚀钢板NS142高镍合金钢 NS142化学成分
NS142 alloy steel description of characteristics and application fields: the alloy is a kind of general engineering alloy, in oxidation and reduction environment all have the high acid and alkali corrosion resistance of nickel composition make alloy has effective resistance to stress corrosion cracking. In all kinds of medium corrosion resistance are good, such as sulfuric acid, phosphoric acid, nitric acid and organic acid, alkali metals such as sodium hydroxide, potassium hydroxide and hydrochloric acid solution. Alloy comprehensive performance in corrosion medium variety of nuclear burning dissolver, such as sulfuric acid, nitric acid and sodium hydroxide were handled in the same equipment. Used in various industrial sectors using temperature does not exceed 550 ℃, such as sulfuric acid pickling factories with the heating pipe, containers, basket and chain, sea water cooled heat exchangers, Marine products such as pipe system, acidic gas pipeline environment, phosphoric acid in the production of heat exchangers, evaporators, washing and impregnated tube, air heat exchanger in the oil refining, food engineering, chemical process, the high pressure oxygen flame retardant alloy, etc
