BBN STEEL supply P355GH steel used for petroleum plate specifications range: thickness 8-650mm, width 1500-4020mm, length 4000mm-17000mm, single weight maximum 30.00 tons. Various special specification sheets can be rolled according to customer requirements. Types of steel products: carbon structural steel pipes, low-alloy high-strength steel sheet, steel angles for bridges, steel section for building structures, steel plates for shipbuilding and offshore platforms, steel for boilers and pressure vessels and alloy structures.

How to distinguish the inferior steel plate? 1. The surface of the fake and inferior steel plate is easy to produce scab. 2. The material of fake and inferior steel plate is not uniform and there are many impurities. The surface of fake and inferior steel plate is often pitted. Pitting is an irregular and uneven defect on the surface of p355gh steel used for petroleum, steel plate caused by serious wear of rolling groove. Due to the pursuit of profit by the manufacturers of fake and inferior steel plates, the groove rolling often exceeds the standard.

Boiler steel plate mainly refers to the hot-rolled medium and thick plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The commonly used p355gh steel used for petroleum, boiler steel is low carbon killed steel smelted in open furnace or low carbon steel smelted in electric furnace, with carbon content in the range of 0.16% - 0.26%.

p355gh steel used for petroleum stock increased rapidly. The social stock of five kinds of steel products (screw steel, wire rod, hot rolled coil, cold rolled coil and medium and heavy plate) in major cities in China was 8.12 million tons at the end of January and 19.05 million tons at the end of February. By the middle of March, the social inventory was 20 million tons, an increase of 13.18 million tons or 193.3% over the end of December last year.
