Forged Alloy Steel Round Bar Grade 1.6587 / 17CrNiMo6 18CrNiMo7-6
Alloy Steel Diameter 20-300mm
Alloy steels are more responsive to mechanical and heat treatments
than carbon steels. They comprise different types of steels with
compositions which exceed the limitations of B, C, Mn, Mo, Ni, Si,
Cr, and Va in the carbon steels.
