Cromamig 312
CEWELD® 312 was developed for welding buffer layers prior to build-up welding of armor plates, exhaust systems, high-manganese austenitic steel, and for heterogeneous welding of difficult-to-weld and unknown steels. Another application is the production of tough joints (one layer) of unalloyed or low-alloy, higher-strength structural steels to manganese hard steel and CrNiMn steels. It is also suitable for build-ups on couplings, gears, shafts, etc., as well as for repairing tools. Max. operating temperature: 300 °C

CEWELD® 312 has a scale resistance of up to 1150ºC, is crack and wear resistant, and is suitable for rebuilding worn parts. CEWELD® 312 has a low tendency to hot cracking and good toughness and strength properties. In addition, the weld metal is cold worked.
