Royal 220-TIG will produce the highest tensile and yield strength on over 50 different steels. These include dies, cast steels, tool steels, stainless steels, spring steels (including vanadium-moly spring steels), nickel clad steels, pressure vessels, dissimilar steels and many other difficult-to-weld steels. Weld deposits have superior crack-resistance even when welding jigs, molds, dies, leaf springs, earthmoving, mining, and construction equipment. Royal 220-TIG forms an extremely strong underlayment or pad prior to applying hard facing alloys. Royal 220-TIG weld deposits are machinable as welded and work harden during use.
