SAE AMS6352J

This specification covers an aircraft-quality, low-alloy steel in the form of sheet, strip, and plate.

These products have been used typically for heat treated parts and structures that may require welding during fabrication, but usage is not limited to such applications. It may be through-hardened to a minimum tensile strength of 180 ksi (1241 MPa) in sections 0.125 inch (3.18 mm) and under in nominal thickness and proportionately lower strength in heavier section thicknesses.
