Avantage of using heat treated BORON material katesi engaging tools
the above technical data shows that the boron type of GET has superior mechanical propertied wiht much higher resistance to wear and abrasion due to the nature of chemical composition,as the result,the lifespan of boron type of GET will be at least twice that of carbon steel.thus,the cost savings on downtime,labour charges and plow bolts and nuts are tremendous.
