The company adopts the P235GH material specification international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety p235gh material specification management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.

Under normal exposure to the atmosphere, p235gh material specification, bare steel forms a tight protective oxide film during the first few months of atmospheric corrosion. Sometimes architects choose bare steel structures because they want to get the appearance of uniform atmospheric oxidation on the steel surface, and sometimes they are to save the protective coating for economic purposes. To use these low-alloy high-strength steels in a bare state, the design must consider that the surface of the steel cannot be wet for a long time, and special attention should be paid to the special atmospheric environment to ensure that the corrosion rate of the steel is allowed under this condition.

Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel, such as strength, toughness, ductility, forming, welding and cutting, abrasion, high temperature, fatigue and so on. The weathering resistance of weathering steel is 2-8 times of that of plain carbon steel p235gh material specification, and the coating property is 1.5-10 times of that of plain carbon steel. Weathering steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving, etc..

30CrMo 35CrMo 25CrMo4 42CrMo4 and so on CrMo steels have good mechanical properties and hydrogen resistance at room temperature and high temperature. The main alloy elements in CrMo steel are molybdenum, chromium, vanadium, silicon, boron, etc. Molybdenum is a very important alloy element in the hot strength steel. It can significantly improve the hot strength of the CrMo steel, maintain sufficient strength at high temperature, refine the grains and prevent the overheating tendency of the CrMo steel, p235gh material specification.

40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. p235gh material specification, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785
