Phosphorus is a very harmful element in P355GH astm equivalent steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of p355gh astm equivalent steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.

Our 12Cr2Mo1VR steel plate breaks through the specification limit, with a thickness of p355gh astm equivalent up to 180 mm and a single weight of 43.7 tons. The flaw detection can meet the highest level of NB / T47013 flaw detection level. Its thickness and unit weight exceed the production limit of vanadium steel. The 12Cr2Mo1VR steel plate with such specifications has high technical requirements, severe performance requirements, and great production difficulties. In the p355gh astm equivalent production process, it is easy to appear the tail area defects, which will cause the steel plate to fail inspection. So please choose your suppliers carefully.
