Washington Alloy, TT 90S-B9 02, Welding Wire, 0.035 in, 36 in, 9% Chromium Steel Alloy, 110,500 psi

ER90S-B9 is a 9% Cr & 1 Mo wire modified with niobium (CB) and vanadium designed to provide creep-rupture strength, toughness, fatigue life, oxidation and corrosion resistance at elevated service temperature and high pressures. This wire is suitable for 9% Chromium steels such as P91, T91, F91 and ASTM A-213, A-335, A-387. Applications include fabrication of turbines, header systems, steam piping, electric generation, and petrochemical equipment. Controlled preheat, interpass and postheat treatment may be needed to avoid cracking.
