Chrome Moly 4130 Sheet
4130 sheet (UNS G41300) is made from quality steel melted to meet the rigid standards of the aircraft industry. It is carefully rolled and inspected to be free from laminations and tears. It is also free from pits, blisters, grooves, and seams, which cannot be removed without reducing its thickness below the minimum permissible dimensional tolerance limits.
