Bisalloy 80 is a low alloy high stregthsteel manufactured with a controlled carbon equivalent for optimum weldability.
Bisalloy 80 can be successfully welded to itself and a range of other steels, provided low hydrogen consumables are used and attention is paid to pre-heat, interpass temperature, heat input and the degree of joint restraint.
Stress relieving can be achieved at 540ºC – 570ºC. Heating above this temperature should be avoided to minimize any adverse effects on mechanical properties. Cold forming can be successfully conducted, provided due account is taken of the increased strength of the steel.
