JIS G3115 SPV355 pressure vessel steel plate is hot-rolled steel plate with improved welding properties. The thickness range of SPV355 pressure vessel steel plate is 6-150mm. Generally, the delivery state of SPV355 pressure vessel steel plate is hot rolling state. However, normalizing can also be used if necessary. TMCP or quenching and tempering are also OK after negotiation between the SPV355 steel plate supplier and the demander.

After negotiation, if normalizing or quenching and tempering are carried out by the demander, the manufacturer can only conduct such heat treatment on the sample, and the SPV355 pressure vessel steel plate can be delivered in hot rolling state.
