UNS N08367 NAS 254NM Stainless
UNS N08367 NAS 254NM Stainless Alloy Steel Plates / ASTM Seamless Steel Coils for Boiler Making
Descrition:
AL-6XN superaustenitic stainless steel seamless pipe UNS N08367 NAS 254NM
General Introduction
AL-6XN is a superaustenitic stainless steel with outstanding resistance to chloride pitting, crevice corrosion and stress corrosion cracking. AL-6XN is a 6 moly alloy that was developed for and is used in highly aggressive environments. It has high nickel (24%), molybdenum (6.3%), nitrogen and chromium contents that give it excellent resistance to chloride stress corrosion cracking, chloride pitting, and exceptional general corrosion resistance. AL6XN is primarily used for its improved pitting and crevice corrosion resistance in chlorides. It is a formable and weldable stainless steel.
Because of its nitrogen content, AL6XN has greater tensile strength than common austentitic stainlesses, while retaining high ductility and impact strength.
Applications:
- Reverse osmosis desalination equipment and pumps
- FGD Scrubbers
- Chemical process tanks and pipelines
- Seawater heat exchangers
- Tall oil distillation columns and packing
- Offshore oil and gas production equipment
- Pulp bleaching plant washers, vats, press rolls and pipelines
