FW1102 62 ~ 65HRC mining, metallurgy, cement, chemical, excavation, road building, dredging, dust, sugar and paper making machinery and equipment wear-resistant surfacing. Mine scraper conveyor such as "middle slot board" and all kinds of "material mixing equipment" and other high wear effect was particularly notable occasions. Has excellent resistance to low stress abrasive wear performance, but not for a serious shock or impact wear conditions, single welding can achieve satisfactory wear life. Be based on the specific use of welding pieces of material or conditions, should be considered when welding the transition layer.
