For use in rolling friction applications, Tr.No.1 consists of Chromium Carbide particles suspended in a refined matrix of high chrome steel. Following a specialized heat treatment,hardness is uniform throughout the material thus giving toughness and long wear. Hardness is adjustable from 36HRC to 60HRC depending on the application. Remachining after use is esaily carried out throughout the complete hardness range.
For use in rolling friction applications, Milten B has been developed to withstand the ever increasing rolling speeds in today's steel mills. Milten B utilizes an equal volume of complex carbides precipitated in a tough stainless matrix, giving excellent wear resistance in the corrosive,abrasive environment encountered in steel rolling. As with Tr.No.1,the material is through hardennable in the range HRC40〜61 depending on service conditions and can be easily remachined after use without any decrease in wear resistance.It is recommended wherever Tungsten Carbide or hardfaced rollers are applicable and also in larger size rollers where Tungsten Carbide becomes uneconomical.While classified as a brittle material Milten B has a Charpy Impact Strength of approximately 4J/cm2,making it more than suitable for guide roller applications.
It is a wear-resistant material which provided wear resistance and toughness by containing a large amount of high hardness MC carbides, and it balanced well.
For use in sliding friction applications,Tr.No.5 consists of copper globules precipitated in an austenitic stainless steel matrix by a specialized heat treatment. The copper globules act as a lubricant and the tough matrix as a high temperature wear resistant material, leading to long service life without the danger of scuffing or galling. Hardness is fixed at HS32-36(HRC15-23). Rematching is easily carried out and rebuilding with stainless steel welding rods is possible over small areas.
