FW8103 58HRC often used stone machinery, dredging machinery, rubber machinery, and other vulnerable parts of the surfacing. Such as: large excavator production gear, crushers pendulum, fans mill around the disk, cross cutting and so on. Surfacing in a direct solderability carbon steel or alloy surface, high impact loads in the good and metal between Abrasive wear performance. 
 FW8104 56 ~ 60HRC no transition layer at the surface of cast iron welding, often used for sugar cane juice machine rolls, cut sugar cane knives, feed grinder blade, the impact of drilling bits, drilling with a chisel, drive pulleys and other components of pushing the surface of the heap welding or repair. Surfacing Air hardening, toughness, crack resistance, suitable for high shock load conditions of Abrasive or metal abrasion conditions.
