diamondspark 900 MC is a seamless, high strength metal-cored wire alloyed with nickel, chromium and molybdenum, with a yield strength above 890 MPa. It is used in machine building, crane structures and commercial vehicles.
Base materials are S890Q, S890QL and ASTM A 709. The seamless construction limits moisture pick-up in the core, the wire goes onto mobile equipment, machine frames and cranes, and it leaves only silicate islands to clean between passes.

Keep the heat input within the range the steel maker specifies, going above it lowers the strength of the joint. Set the parameters for spray arc, in the short arc range a metal-cored wire loses its deposition advantage. Keep the gas cover complete, without a full slag layer the pool is more sensitive to draughts.
