Chrome Moly 4130 Plate
Hot rolled normalized or annealed 4130 Plate 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 tits thickness below the minimum permissible dimensional tolerance limits.
