Hi guys, I've been looking at some of the material studies and found grades of maraging steel of 3000 mpa and above tensile strength from the 70s. Apparently they are 13% Ni whereas most of the maraging steels today are 18%. Where are these steels today? Are there any suppliers? This stuff would be perfect for one of my projects but highest i can find are 350 grade of the 18% Ni kind
