Washington Alloy, TT 120S-1 03, Welding Wire, 0.045 in, 36 in, Alloy ER120S-1, 100,000 psi YS, 125,000 psi TS

ER120S-1 is used for a variety of steels where high strength and ductility are critical. It is designed to give high notch toughness, yield strength and impact resistance. ER120S-1 can be welded at an interpass temperature as low as 300°F while also offering high ductility to -75°F. Typical application may be high yield steels such as T-1, HY-100 and other steels in the 100,000 psi YS class, pressure vessels. Mechanical properties from the weld deposit will vary depending on heat input used. Preheat and interpass of 300°F may be required.
