Description

Our patent products with independent research and development (China Patent No. ***********1.2) **- Bimetal thermal-composite material
This product adopts special and professional process and method to combine two different performance of material in molten condition at the same time to melt as a whole one. The interface of combining is up to **0%. Its working end is of high chromium cast iron material to effectively ensure adequate performance of anti-friction; its assembling end is of alloy steel material of good tenacity to assure the safety of running. The hardness of bimetal thermal-composite material is up to HRC****5. Its impact ductility is over (AK) *0J/cm2. It has high anti-friction effects and reliable security.
This effectively solves the contradiction between the hardness and ductility to meet and adapt to a variety of complex and harsh working conditions.
