HORDA 307Si is recommended for buffer layers before surfacing and for surfacing a wear-resistant layer that self-reinforces under load. The weld metal, in addition to self-reinforcing under load, has excellent cavitation resistance, heat resistance and scaling resistance up to 850 ° C. The weld metal also has high resistance to cracks. Wire can be used both in combination with shielding gas, and with neutral and basic fluxes (ceramic and fused), providing the required composition of weld metal. Flux grade and welding technology is chosen by a specific production technologist.
