Atom Arc 9015-B91
Atom Arc 9015-B91 is designed to weld martensitic 95% Cr & 1% Mo-V steels known by the designations T91, P91 or Grade 91. These steels are designed to provide improved creep strength, fatigue, oxidation, and corrosion resistance at elevated temperatures. It also provides good weld metal ductility and high charpy values at room temperature. This product is optimized to meet the requirements for Mn + Ni contents <1.0 wt %.
