Features of Motor Grader Cutting Edge
1. The material options for our motor grader cutting edge include high carbon steel and high quality boron steel. There are curved blades and flat blades available.
2. With thickness range from 13mm to 75mm, and width from 152mm to 406mm, the cutting edge is suitable for all kinds of graders domestically and overseas.
3. Process of hot-pressing and compression bending is applied in all grader end bits which are made from boron steel.
4. The product undergoes quenching and tempering treatment, with performance up to the international standard.
5. We provide high quality serrated grader blades that offer CNC cutting.
6. Also we provide motor grader cutting edge of overlay welding (with special material). The wear resistance is three times better.
7. With stable performance, strong abrasion resistance and high performance-price ratio, our cutting edge products will be your ideal choice.
Heat treated, through-hardened boron steel, hardness range is HB420~HB500. It delivers maximum protection against breakage in high impact applications. At the same time, it delivers high abrasive protection.
