Hardmelt 620 is our rutile coated electrode for wear-resistant surfacing tool steels subject to metal-to-metal wear at elevated temperatures up to 550ºC. Deposit weld metal is a high-speed steel (HSS) similar to M-1 tool steel, the structure is fine precipitated carbides in a martensitic matrix, the hardness of pure weld metal is 62 HRc. This hardness can be increased after tempering. After welding the deposit can be machined by grinding only
