Its working surface wear-resisting material is the surface with hard alloy column, and the surface with Diamond complex, hardfacing electrode and low temperature brazing article hard alloy and others. It adopts AISI 4145H Mod alloy steel, executive API standard and SY 5051 standard, having excellent mechanical properties.
Applications:
Integral spiral blade stabilizer is using spiral way to strength the body resistances and it includs the bottom of a well type and the drill string type, making the thread rolling cold, copper or phosphorus treatment.
