RA 410
Because 410 is an air hardening steel, it must be given a high preheat, at least 350-400°F before welding, and immediately given a full anneal before the weldment cools. Otherwise the metal will harden, and cracking is likely. Matching composition filler metals are available, AWS E410 covered electrodes and ER410 bare filler wire. Alloy 82 (AWS ERNiCr-3) filler wire has also been used. This nickel alloy is comparatively low strength, and therefore accommodates some of the strain which may otherwise contribute to cracking in the 410 weldment.
