P265GH material and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of p265gh material and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.

p265gh material product plate specification range: Thickness 3-150mm Width 1500-4020mm Length 4000mm-17000mm Heat treatment: annealing, or normalizing and tempering

Try to use p265gh material high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the p265gh material temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

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 p265gh 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.
