Characteristics and field of use Due to its high-grade structure, UTP 702 is used for repair, preventive maintenance and production of highly stressed cold and hot working tools, such as punching tools, cold shears for thick materials, drawing -, stamping - and trimming tools, hot cutting tools, Al-die cast moulds, plastic moulds, cold forging tools. The weld deposit is, in as-welded condition, easily machinable and the subsequent age hardening opitmises the resistance to wear and alternating temperatures. UTP 702 has excellent welding properties, a smooth and regular drop transfer, good bead appearance and easy slag removal. Hardness of the pure weld metal: untreated: 34 – 37 HRC After age hardening 3 – 4 h / 480° C 50 – 54 HRC
