• This chromium-molybdenum alloy is one of the most widely used aircraft steels because of its combination of weldability, ease of fabrication, and mild hardenability. In relatively thin sections it will respond to heat treatment to high strength levels and yet in the normalized condition it has adequate strength for many applications. When resistance to wear and abrasion is required, it may be nitrided.
    This grade is a quality product melted under the best steelmaking practices for aircraft quality steels. It is vacuum degassed to meet the magnetic particle inspection standards of AMS 2301.

  • 4130 sheets and plates are made from quality steel melted to meet the rigid standards of the aircraft industry. They are carefully rolled and inspected to be free from laminations and tears. They are also free from pits, blisters, grooves, and seams which cannot be removed without reducing their thickness below the minimum permissible dimensional tolerance limits.
