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 P235GH equivalent astm 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.

Q345R steel plate is a special steel for pressure vessel with yield strength of 340Mpa. p235gh equivalent astm material, Q345R plate has good comprehensive mechanical properties and processing properties. The content of phosphorus and sulfur of Q345R material is slightly lower than that of Q345 (16Mn) steel. In addition to the higher tensile strength and elongation requirements than Q345 (16Mn) steel, Q345R steel is also required to ensure the impact toughness. p235gh equivalent astm material, Q345R pressure vessel steel plate has wide application and considerable consumption in China.

In September, China's apparent consumption of crude steel was 94.38 million tons, an increase of 15.58 million tons or 19.8% year-on-year. It has exceeded 90 million tons for five consecutive months. From January to September, China's apparent crude steel consumption was 770 million tons, an increase of 63.14 million tons or 8.9% year-on-year. In terms of growth rate, the apparent consumption of hot-rolled sheet and coated sheet (strip) from January to September increased by more than 40% year-on-year, and the growth rates were 42.6% and 42.0% respectively; railway steel and electrical steel strips fell year-on-year, with a decline. They are 12.8% and 1.4% respectively.
