The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, A514 grade H alloy steel plate professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better A514 grade H alloy steel plate tomorrow!
Carbon steel SA516Gr70 corresponding material is SA516 Gr485 steel. SA516 Gr485 is called according to the min. tensile strength 485MPa. Our company can supply A514 grade H alloy steel plate, ASME SA516Gr70 carbon steel plate and sheet with thickness ranging from 5mm to 150mm. SA516Gr70 steel plate for pressure vessels and boiler is delivered in hot rolling, controlled rolling, normalizing, while plate thickness greater than 40mm must be normalizing.
The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of A514 grade H alloy steel plate, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.
The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of A514 grade H alloy steel plate nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of A514 grade H alloy steel plate steel, can be used as an alloying element of low alloy steel.
P235GH steel material number under EN10028-2:2003 standard is 1.0345. This steel is a European pressure vessel steel.
