This product adopts 20CrMo alloy structural steel material, CNC machining center, surface roughness Ra3.2, machining tolerance +/-0.08.
Due to high hardenability of 20CrMo, no temper brittleness, weldability is quite good, the tendency to form cold crack is very small, machinability and cold strain plasticity is good.
The surface is cleaned and degreased, and then it needs to be hardened.
Blister box + carton packing shipment.
