AISI 4130 Low Alloy Steel

Pipe, Fittings, Flanges, Plate, Bar, Tube

Applied Alloys International is Australia’s premier source of AISI 4130  material. 

AISI 4130 / UNS G41300 grade is a low alloy steel containing chromium and molybdenum as strengthening agents. The steel has good strength and toughness, weldability, and machinability. AISI 4130 finds many applications in oil & gas, offshore, mining, and aerospace industries. 1.7218 – 25CrMo4 – 25CD4(S) – JIS G4150 Gr SCM430
