Is stress relieving needed
Is stress relieving needed
(OP)
Dear members,
Is stress relieving required for large castings (1.5m x 1.5m x 1.0m), weighing about 1.5MT. The material is SG400. Can the SR be done after machining process or is it mandatory to do the SR before machining. Can vibratory stress reliving be adopted instead?
Any literature on this subject will also help.
Thanks

Most of the time, the client's engineering specification will provide the above requirements.
