2,Hardness and toughness of the steel body:special heat treating and hardening to achieve the optimum hardness and to keep the necessary ductility.
3,Great brazing strength to combine the carbide tip and the steel body firmly together.
4,Quality control:inspection during the production and test after the production are performed for consistent quality.
Our company can provide you with these specifications:
For other specification, we can customize upon request.
Place of Origin: Shandong China
Color: Customized according to customer requirement
Our principle
1. According to the technical drawings using standard material specification productio
2. Competitive price and products
3. tungsten carbide with reinforcement coal mining drill bits
4.continuous miner, long wall shearing, roadheader
The teeth body is made of high quality cold extrusion 42CrMo, high density not decarburization. Numerical control lathe processing ensures consistent size. With special heat treatment process of 40-45 degrees, its surface is almost no oxidation, tooth head using isothermal quenching process, its hardness doesn't reduce. Production of cemented carbide by formal domestic companiesYG11C, stable quality can accord customer needs to add welding wear-resisting layer, hardness reaches more than 65 degrees.
