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.
