coilaeronauticalfor the aerospace industry

An Austenitic Stainless Steel with manganese and nitrogen additions Enhanced mechanical properties in annealed condition; high potential for elongation and hardening; very good resistance to intergranular corrosion; excellent weldability; high ductility; excelent strength and toughness at cryogenic temperatures. Applications Railroad and transportation Cryogenic tanks, storage vessels and piping High performance welded structures including those at sub-zero temperatures In general all applications where austenitic grade 1.4318 (Type 301LN) is used, with the added advantage of price stability due to the lower nickel content Norms ASTM 201LN UNS S20153 EN 1.4371 IMDS ID 336855939 Chemical Composition Typical values C=0.025 Si=0.50 Mn=7.00 Cr=16.30 Ni=4.75 N=0.18 Cu=0.30 Surface aspects Hot rolled & Cold rolled 1D, 2B, 2D, 2E
