Weldtool tool steel type S-7 is a A.I.S.I. type S-7 shock resisting tool steel alloy. The as welded hardness of the deposits will typically be 55–60 HRC which can be tempered to lower hardness when necessary. This alloy works well in cutting or shearing environments at room temperature due to its unique ability of having high strength and being tough. Weldtool tool steel type S-7 is recommended for welding A.I.S.I. S-7 tool steel, however, because its weld deposits can be tempered to various hardness values, it can also be used to repair other shock-resisting grades plus many types of water-hardening tool steel. Tool steel type S-7 works exceptionally well on metal stamping blank trim and pierce dies where edge chipping causes burr on parts. Tool steel type S-7 is an ideal electrode for building cutting edges on composite cold and hot trim sections and punches.
