Product Introduction

ASTM B622 UNS N08031 Pipe is a nitrogen-containing iron-nickel-chromium-molybdenum alloy with properties between the super-austenitic stainless steels and existing nickel-based alloys. W.Nr. 1.4562 alloy has excellent resistance to a wide range of chemicals, including hydrochloric acid, sulfuric acid, phosphoric acid, and many other highly corrosive solutions. Alloy 31 (N08031, 1.4562) is a combination of medium tensile strength, high ductility, and excellent corrosion resistance.
