Corrosion-resistant tungsten carbide of KW120 tungsten steel round bars long tungsten steel plate

Kennametal was established in 1938 to the present, has been 500 carbide manufacturing patent. To ensure that products from start to finish with the best quality, to Kenner own smelting ore, grinding of raw materials, and with the powder, pressing, sintering, grinding / polishing, it will give Kennametal has a flexible capacity to produce various grades of materials and finished products to more good to meet specific customer requirements. KezizTM sintering process is one of the Kenna patent, the use of this unique process, Kennametal has become the world's first large-scale production of surface and internal virtually defect-free tungsten carbide / carbide materials manufacturers. Unrivaled quality assurance system, testing equipment and industry experience, Kennametal products and the level of detection can reach the standard of military and nuclear industries. Kennametal's goal is to ensure that the products are the perfect products to customers every time from Kennametal. 
 Generic brands of CD-650 Kennametal in a classic grade stamping die industry, with excellent cost more than ten years of history in North America, Europe and China markets. 







 CD-650 because of its excellent performance has been widely used in precision stamping dies, CD-KR887 on the basis of the CD-650, that is maintained CD650 excellent performance, but also demonstrated excellent in electrical discharge machining processing performance. 



 CD-KR887 material design point of departure is able to withstand the harsh environment for electrical discharge machining. When the ordinary tungsten carbide material for a long time exposed to electrical discharge machining environment, corrosion, pitting and discoloration as well as micro-cracks in the exposed surface. Such defects will result in the loss of material strength by up to 60%. Extreme EDM conditions, of Kennametal CD-KR887 material after 100 hours of discharge processing is still no pitting, cracks and discoloration, and in the processing, able to withstand coolant, mold lubricant corrosion and acid gases. 



 Higher corrosion resistance - 100 times higher than normal carbide the corrosion resistance 
 Excellent mechanical properties 
 Outstanding resistance to electrolytic corrosion 
 Resistance to chemical corrosion 
 Reduce discharge machining time 
 Hot isostatic pressing and stress release process
