Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and usage of P295GH steel resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, usage of p295gh steel new materials, and promotes the competition of enterprises Struggle.

Carbon steel usage of p295gh steel is an iron carbon alloy with carbon content less than 2.11% and a small amount of silicon, manganese, sulfur, phosphorus and other impurities. Carbon steel inevitably contains some impurity elements during smelting, which has a great influence on the performance and quality of steel, so it should be controlled. The quality of carbon steel is mainly measured by the content of sulfur and phosphorus. The lower the usage of p295gh steel content of sulfur and phosphorus, the better the quality of carbon steel.

Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the usage of p295gh steel steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the usage of p295gh steel steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This usage of p295gh steel method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. usage of p295gh steel, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
