Hydrogen (H) is the most harmful element in general steel such as P355GH astm equivalent. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.

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.

The company now has p355gh astm equivalent oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than p355gh astm equivalent 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

We have a large number of p355gh astm equivalent steel materials in stock, and provide deep processing services such as welding. In addition to simple welding parts, we can also weld H-beam, box column and other profiles. For such welded structure, our advantage is that there are high-quality and low-cost raw material steel plates, which can be cut into the p355gh astm equivalent required size and welded into steel products with required shape and size, without being limited by the specifications of rolling production lines.
