ER90S-B3 AWS A 5.28 CLASS ER 90S-B3
ER90S-B3 is a low alloy wire used to weld 2¼% Chromium, 1% Molybdenum low alloy steels.
ER90S-B3 produces quality welds on pressure piping or boiler work.
Depending on the hardening characteristics of the base metal, pre-heating from 400°F - 650°F, control of interpass temperatures and post heating at 1,250°F - 1,350°F for 1 hour is required.
Typical applications include pressure piping in steam power generating plants, boiler and heat-exchanger tubes, chemical and petrochemical processing equipment, and shipbuilding.
Tensile strength: 103,000 psi.
Elongation is 24%.
Charpy V-notch @ 72°F is 85 ft. lbs.
