SAF Steelcored 58 description: STEELCORED 58 is a seamless copper coated basic flux cored wire for the hardfacing of wear parts, such as excavator parts, scraper blades, dipper teeth, worm conveyors, beaters, crusher jaws, crusher cones, subjected to heavy wear. The weld metal is tough, free of cracks and therefore resistant to shock and impact. Machining is only possible by grinding. A tough buffer layer using STEELCORED 31 is only required with highly hardenable base plates.
