SA612M is a kind of low temperature pressure vessel welding C-Mn-Si steel plate with sedation.
Set: low temperature pressure vessel welding
Scope of application: low temperature welding pressure vessel Wugang implementation of the standard WYJ059-2006
SA612M is a kind of medium and low temperature welding pressure vessel with calm C-Mn-Si steel plate
The main technical conditions of SA612M are as follows
Scope of application of this technical agreement applicable to the maximum thickness of 25mm in low temperature welding pressure vessels used to calm the production and inspection of C-Mn-Si steel plate. Reference standards for the implementation of the Wugang standard WYJ059-2006 allows the deviation of the size, shape, appearance, and allow the deviation of the implementation of the requirements of 20M SA. technical requirement
