The company adopts the q345r steel 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 q345r steel 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.
SA516Gr45 (R-HIC) This type of steel plate is mainly used in the manufacture of equipment used in wet hydrogen sulfide environment, such as: liquefied petroleum gas desulfurization system, stable absorption system for catalytic cracking, condensation system of atmospheric and vacuum distillation tower, etc. The material q345r steel has the characteristics of high purity, low P, low S, good uniformity of structure and mechanical properties, resistance to hydrogen cracking and sulfide stress corrosion.
20G steel is boiler steel, which is similar to No. 20 carbon steel. The difference is that 20G steel has higher and stricter inspection standards than q345r steel, No. 20 carbon steel for harmful impurities and internal defects. That is to say, 20G steel is specially produced for boiler pressure vessels. It is special purpose "No. 20 carbon steel". The use of 20G steel to make boilers is not because it is more resistant to burning than other steels such as q345r steel, but because of its strength, toughness, ductility, weldability, temperature influence, fatigue fracture, price and cost, etc. 20G steel is most suitable for use in medium and low pressure boilers.
A small amount of Nb is sufficient to obtain excellent comprehensive properties of q345r steel etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.
q345r steel 2020 spot size: 16*1800*6000, 15*2500*10000, 25*2400*8200, 50, 25*2400*8200, 16*2000*10713, 25*2400*8200, 16*2270*11900, 15*2500*10000, 25*2400*8200, 28*2170*13000, 130*2200*7700, 100*1770*6650, 88*3440*9200, 12*2200*8000, 8*2200*5730, 16*2320*10000, 30*2400*9680 12*2200*8000, 16*1800*6000, 50*1820*10700, 130*2200*7700.
Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled q345r steel plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive q345r steel industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
