JIS SM400C plates, cutting parts stock

The company supplies more than 2,000 tons of pressure vessel steel materials to the Nigerian customer for the construction of atmospheric pressure tower in the refinery. This batch of JIS SM400C plates pressure vessel steel materials are tailored according to customer requirements, and the composition and process are newly designed. The performance of the pressure vessel steel materials meets the requirements of properties such as resistance to tempering embrittlement and hydrogen corrosion, and JIS SM400C plates special properties such as good formability, weldability and adaptability to welding process.

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 JIS SM400C plates, 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.
