CEWELD® 310 for joining and build-up welding on heat-resistant steels/cast steels of the same or similar type. Somewhat more susceptible to hot cracking due to fully austenitic weld metal. Typical applications include industrial furnaces, annealing chambers, salt bath treatment equipment, boiler parts, and heat exchangers.

CEWELD® 310 is a corrosion-resistant and heat-resistant solid wire for welding austenitic steels with a Cr content of 25% and a Ni content of 20%. Due to its high Cr content, CEWELD® 310 has good general oxidation resistance, especially at high temperatures. The alloy is fully austenitic and therefore sensitive to hot cracking. The temperature limits for use in intermittent oxidation depend on the cycle frequency. Under no circumstances should a temperature of 1000°C be exceeded. This alloy can withstand relatively severe thermal shocks and is superior to type 309 L.
