Our cutting edges and grader blades are designed for bulldozer and motor grader .The material is carbon steel(45# or 80#) and boron steel(16MnB or 30MnB),the hardness is about HRC42-HRC45.At the same time,these products are optional to be made by both high carbon and boron steel that are heat-treated and hardened to improve the lifespan while meeting the demanding requirements of earthmoving and mining applications.For example,Caterpillar,Komatsu,D275,D475,D155,D65 etc.
And we could supply the OEM service,design and make the cutting edge & blade by the drawings from the customers.
