Mac HSS E3062
High Speed Steel
Descriptions & Applications:
Hard facing electrode, designed to deposit high quality high speed steel on mild or low alloy steels, having a metal recovery rate of 115%. Tough and highly crack resistant deposits, retaining hardness at temperatures up to 620°C. Deposits can be annealed and re-hardened by oil quenching. Highly recommended for the fabrication of blanking and piercing dies, knife blade edges, shear blades, lathe tools, boring tools, milling cutters, broaching tools, drills, hot working dies etc., ideal for the building up of edges on small components.
