The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating astm a573 gr 70 equivalent carbon steel iron plate production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.
Whose hardness is higher between No.20 steel and No.45 steel, astm a573 gr 70 equivalent carbon steel iron plate? Both No.20 steel and No.45 steel belong to high-quality carbon structural steel. According to the characteristics of high-quality carbon structural steel, its carbon content determines the performance of the steel. The higher the carbon content, the higher the hardness and strength of the steel, the lower the plasticity and toughness. The carbon content of No.20 steel and No.45 steel are 0.20% and 0.45% respectively, which shows that the hardness of No.45 steel is higher under the same process.
astm a573 gr 70 equivalent carbon steel iron plate, Q345D seamless pipe is low-alloy high-strength structural steel. It is named as low-alloy because of a small amount of alloy elements in the steel. Q345D seamless pipe is mainly used for construction and engineering structures. The carbon content of Q345D seamless pipe is ≤ 0.18%. Due to the effect of alloy elements, the yield strength of Q345D seamless pipe is 25% - 150% higher than that of carbon structural steel pipe with the same carbon content. Q345D seamless pipe can reduce the weight of steel structure, save steel products and effectively extend the service life of steel structure.
Slow heating, preheating and other balanced heating methods can be used to reduce the heat treatment deformation of wear-resistant composite plate. Correct heat treatment process and reasonable tempering heat treatment process are also effective methods to reduce the deformation of wear-resistant composite plate. There are many reasons for the deformation of wear-resistant composite plate, astm a573 gr 70 equivalent carbon steel iron plate. We only need to master the deformation law and analyze the reasons. The deformation of composite wear-resistant plate, astm a573 gr 70 equivalent carbon steel iron plate can be alleviated and controlled.
According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. astm a573 gr 70 equivalent carbon steel iron plate, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.
