The company now has 1 inch sa573gr.70 carbon plate oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments
The company now has 1 inch sa573gr.70 carbon plate oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than 1 inch sa573gr.70 carbon plate 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.
The yield strength of A36, D36, E36 and F36 is not less than 355N/mm^2, and the 1 inch sa573gr.70 carbon plate tensile strength is 490~620N/mm^2. A, D, E and F respectively indicate that they can be at 0° and -20 ° respectively. Impact toughness that can be achieved at -40℃, -60 ℃.
Just as 1 inch sa573gr.70 carbon plate, the boiler steel plate also has strict control of chemical composition for the material, especially harmful elements such as phosphorus and sulfur, and residual elements such as chromium, nickel, and copper; during smelting, good deoxidation and removal of non-metallic inclusions should be carried out to ensure good quality, plasticity and toughness. The organizational structure requires uniformity, and the grain size is controlled within a certain range; there are also strict requirements for surface quality and internal defects. In addition, the boiler steel plate mechanical properties at room temperature and high temperature must be guaranteed.
Corrosion resistance mechanism of 1 inch sa573gr.70 carbon plate, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.
40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. 1 inch sa573gr.70 carbon plate, 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
