1.Product Description:
l Gas shielded hardfacing flux cored wire.
l Hardness can reach 60HRC as welded over 3 layers.
l The deposited metal is high chromium alloy with excellent abrasion wear resistance. Mo,W, V and other elements can improve its high temperature resistance.
l The fine crack appeared during welding is caused by stress releasing, which won’t influence the usage of the components under low impact working conditions.
2.Application:
Suitable for components that withstand heavy abrasion wear at high temperature, such as, single tooth crusher, sintering grate, distribution chute etc.
