Delivery status of P355NL2 steel plates, P265GH pressure vessel steel:A. Normally, the P355NL2 steel plates are delivered in normalized state. According to the negotiation between the supplier and the demander, normalizing rolling can be used instead of normalizing. In this case, the samples should be simulated normalizing according to the agreed test frequency to verify that the performance meets the requirements.B. P355NL2 steel plates shall be delivered by shearing or flame cutting.

Titanium microalloying is an element of p265gh pressure vessel steel strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in p265gh pressure vessel steel tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.

Vanadium mainly exists in the form of carbide in p265gh pressure vessel steel and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

Hot Rolled Plates Products TestingBBN STEEL can supply many tests and analysis done to examine them before and after the manufacturing. As the p265gh pressure vessel steel raw material is fetched by us the steel undergoes vacuum treatment, product analysis, additional tensile test, simulated post weld heat treatment, and impact test. After the steel is converted to steel plates they undergo the drop-weight test, hot tensile test, ultrasonic test, the practical examination through examination, and the vacuum carbon deoxidized steel."
