NS142 NS333 Stainless Steel Mechanical Tubing

NS142 alloy is a general engineering alloy that is resistant to acid and alkali metal corrosion in both oxidizing and reducing environments. The high nickel content gives the alloy effective resistance to stress corrosion cracking. It has good corrosion resistance in various media, such as sulfuric acid, phosphoric acid, nitric acid and organic acids, alkali metals such as sodium hydroxide, potassium hydroxide and hydrochloric acid solution. The higher comprehensive performance of 825 alloy is demonstrated in nuclear combustion dissolvers with various corrosive media, such as sulfuric acid, nitric acid and sodium hydroxide, all processed in the same equipment.
NS333 is a tungsten-containing nickel-chromium-molybdenum alloy with extremely low silicon and carbon content. In the oxidized and restored state, it has excellent corrosion resistance to most corrosive media. Excellent resistance to pitting corrosion, crevice corrosion and stress corrosion cracking. NS333 alloy contains a large amount of elements such as Cr and Mo and has a single-phase austenite structure. Corrosion-resistant alloys have many excellent properties, including good oxidation resistance and moderate reductive corrosion. It has excellent resistance to stress corrosion cracking and localized wear, and has satisfactory corrosion resistance in many chemical process media, including constant strength inorganic acid solutions, chlorine and chlorine-containing media, dry chlorine, formic acid and Soaking in acetic acid, sea water, brine, etc.
