SA514 grade B steel material Normalized PVQ Plate

The steel grades SA514 grade B steel material of thick steel plate are basically the same as those of thin steel plate. In terms of steel types, in addition to the bridge steel plate, boiler steel plate, automobile manufacturing steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate, some kinds of SA514 grade B steel material steel plates, such as automobile girder steel plate (2.5-10 mm thick), checkered steel plate (2.5-8 mm thick), stainless steel plate, heat-resistant steel plate, etc., are crossed with the thin plate.

Ordinary medium and thick steel plate SA514 grade B steel material is a kind of deoxidized steel. The oxygen content of the steel liquid is relatively high, and a lot of gas will be produced during the production process to make the steel liquid boil, so it is also called boiling steel. Advantages: this kind of steel plate has smooth surface, good quality and easy processing. Because this kind of steel plate has no concentrated shrinkage cavity, the amount of deoxidizer is very small and the price is lower than other steel plates.

The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for SA514 grade B steel material pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common SA514 grade B steel material carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.

It is a modern high-tech professional enterprise integrating scientific research, SA514 grade B steel material production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as SA514 grade B steel material process technology development, technology transfer and related technical consulting and technical services.

Our company will accept the product quality objection registration record, pass it to the SA514 grade B steel material production unit and relevant departments, and timely coordinate the supervision of product SA514 grade B steel material quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
