What is the process principle of 34CrMo4 steel and 20MnB5 alloy steel
Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and 34CrMo4 steel and 20MnB5 alloy 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, 34CrMo4 steel and 20MnB5 alloy steel new materials, and promotes the competition of enterprises Struggle.
The main varieties of hot-rolled steel plates are ordinary carbon steel, low alloy steel, container plate, weathering steel, pipeline steel, hot-rolled steel strip for automobiles, ship plate, gas cylinder steel, boiler and pressure vessel plate, 34CrMo4 steel and 20MnB5 alloy steel. Hot-rolled steel strips are processed into different finishing lines to become steel plate, flat coil and slit steel strip products. Our hot-rolled steel plates are widely used in automobiles, machinery, ships, bridges, construction, pressure vessels, pipeline transportation, automotive industry.
Welded pipe, also known as welded steel pipe, refers to the steel pipe made of steel plate or strip steel after crimping and forming, with a fixed length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are diversified, and the equipment investment is less, but the general strength is lower than that of seamless steel pipe. 34CrMo4 steel and 20MnB5 alloy steel, Welded pipes have many uses and are almost ubiquitous in our lives. However, when choosing welded pipes, we must pay attention to performance and material characteristics.
After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of 34CrMo4 steel and 20MnB5 alloy steel, low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.
ASTM A537 class 1 boiler plate is pressure vessel steel. 34CrMo4 steel and 20MnB5 alloy steel, A537 class 1 boiler plate chemical elements include C, Si, Mn, P, S, Mo, Ni, etc. Among them, the carbon content is 0.24 max., Si content is 0.13-0.55%, Mn content is 0.92-1.72%, the max. contents for both P and S are 0.035%, the Mo content is 0.09% max, and the Ni content is 0.38% max. A537 class 1 boiler plate properties: A537 class 1 boiler plate tensile strength is 450-585 MPa, min. yield strength is 310 MPa, and min. elongation in 2 in.(50mm) is 18%.
Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s 34CrMo4 steel and 20MnB5 alloy steel domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.
