If A 515 grade 70 pressure vessel plates thick in 50mm or under this thickness, A514 grade Q high strength steel plate, A515 Grade 70 plates are supplied in the as-rolled condition. Normalizing treatment can be ordered, but those greater than 2 inch (50 mm) in thickness must be delivered in normalizing state. A515 Gr 70plate and sheet are widely used in petroleum, chemical industry, power station, boiler and other industries. It is used to make reactor, heat exchanger, separator, spherical tank, paint tank, liquefied gas tank, nuclear reactor pressure shell, boiler drum.

And will continue to provide customers with high-quality steel products and good service. We sincerely welcome new and old customers to join hands with our company A514 grade Q high strength steel plate and seek common development!
Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the A514 grade Q high strength steel plate plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.
The effect of alloy elements of A514 grade Q high strength steel plate, Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.
Provide special product requirements to meet the personalized needs of customers. The A514 grade Q high strength steel plate company arranges production and shipment strictly according to the contract, and guarantees to supply goods according to the time agreed in the contract. Provide professional consultation: we guarantee to answer any professional and A514 grade Q high strength steel plate technical questions raised by users within 1 hour; provide detailed information.
