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 grade P235GH steel material, 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.

This week, the price of grade p235gh steel material futures rose sharply, and the market mentality was positive. On the one hand, the recent arrival of steel mills is still not much, which has a certain support for the price. On the other hand, the business confidence in the future market is gradually restored, and the willingness to support the price is strong. Today, the move up momentum of grade p235gh steel material futures weakened. In the short term, there may be a slight adjustment pattern, but the probability of a sharp decline is small. It is expected that the grade p235gh steel material market will be mainly volatile tomorrow.

The toughness of steel such as grade p235gh steel material is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.

Hydrogen corrosion is a common problem in petrochemical hydrogenation unit. Decarburization, hydrogen bulging and hydrogen induced cracking often occur in common carbon steel in high temperature (> 232℃) and high pressure hydrogen rich environment. In hydrogen corrosion environment, hydrogen sulfide stress corrosion and uniform corrosion are often accompanied. The prerequisite to overcome hydrogen corrosion is to add Cr-Mo alloying treatment in the steel, grade p235gh steel material.
