Product Description

34CrAINi7-10 round steel is the European standard steel number, which belongs to the medium carbon alloy structural steel and high-quality nitriding steel. Different from the domestic 38CrMoAI material, the steel composition has about 1.0% more nickel element (Ni), and there is no corresponding grade. (More special steel can pay attention to me oh) Gulas has German standard 34CrAINi7-10 hot-rolled annealed round steel, forged bar and other specifications.
