About YASSIAN 

Our main products are grader blades, cutting edges and bucket teeth. Grader blades are mainly applied on motor graders. For grader blades, we can provide C80 (carbon steel) and 30MnB (heat-treated boron steel). The hardness of carbon steel is HB280-320 and the hardness of heat-treated boron steel is HB440-480. It means that grader blades made by 30MnB have higher wear resisting and could be used longer. There are two widths for grader blade - 152mm and 203mm and four thicknesses- 13mm, 16mm, 19mm and 25mm, According to width to classify, normal types are 152*13mm, 152*16mm, 152*19mm and 203*16mm, 203*19mm, 203*25mm. The length could be customized based on model size of machine, but the hot sales are 1828*152*16, 1828*152*19, 1828*203*19, 2133*152*16, 2133*152*19 and 2133*203*19. There are 13 steps in production process of grader blades. Starting with CNC cutting, Polishing, CNC drilling round holes, Punching square holes, Heat treatment, In process quality inspection and then Shot blasting, Straightening, Inspection, Painting, Painting Inspection, finally Packing &Warehouse. 30MnB need to take heat treatment to get high hardness, C80 have too many carbon which cannot take heat treatment to become harder. Hence, clients need to choose right size, material and part number based on machine model and working environment.

Cutting edges are widely used on bulldozers, loaders, motor graders and excavators. For cutting edge, 16Mn (heat-treated manganese steel) and 30MnB are generally used as material. the hardness of manganese steel is HB330-370, which is lower than 30MnB. So if the working environment is bad like mining, choosing grader blades made by 30MnB will be better choice. There are mainly three types: NBF, SBF and DBF cutting edges. The sizes of cutting edges are too many to count, usually we will produces based on the information clients provide. The monthly output of our cutting edge is more than 600 tons. There are 14 steps in production process of cutting edge, that have 1 step more than grader blades -Milling bevel. There are also three inspections during production process, In process quality inspection is the most important one after Milling bevel and Heat treatment. We have professional inspectors to supervise the quality of goods in- process, including checking the shape, all dimensions and the hardness. Finally we also have a final inspector to check everything(dimension,holes distance and hardness)before packing.

Flat edge - Best suited for applications that do not require moving material for redistribution, and for applications for ditching or general gravel maintenance

Serrated edges - Best suited for applications that require increased ground penetration to move surface materials

Curved Edges- Best suited for applications that load and redistribute existing materials along the top layer to create a smooth, flat finished pavement

Scarifier Edges - Most suitable for applications with high ground compaction, heavy stones, asphalt or thick ice.

Weld in and Bolt on cutting edges and other wear componentry is available for all makes and models of Excavators, Bulldozers, Loaders, Scrapers, Graders and Compactors. We can fabricate any type of edge to best suit your requirements.
