Here are 7 ways that steel can fail as a result of Quench Cracking from heat treatment. Overheating during the austenitizing portion of the heat treatment cycle can coarsen normally fine grained steels. coarse grained steels increase hardening depth and are more prone to quench cracking than fine grain steels. Avoid over heating and overly long dwell times while austenitizing.

Weld metal cracks are caused by high localized stresses in the joint arising from the shrinkage of weld metal, by resistance of movement of the parts, or by vibration of the structure during welding. Hence, it is important that each weld run is strong enough to withstand the shrinkage and allows as much freedom of movement as possible. Longitudinal weld cracks usually occur in the root run and ...
