Laser cutting chemical composition of S235J0W plate has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the chemical composition of S235J0W plate cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.
40Cr alloy belongs to gb3077 "alloy structural steel". The carbon content of 40Cr steel is 0.37% ~ 0.44%, which is slightly lower than that of 45 steel. The content of Si and Mn is equivalent, and the content of Cr is 0.80% ~ 1.10%. In the case of hot rolling supply, the 1% Cr basically does not work, and their mechanical properties are roughly the same. Because the price of chemical composition of S235J0W plate is about half of that of 45 steel, 40Cr is not needed for the purpose of economy.
Our company has sales department, technology department, quality inspection department, after-sales department, logistics department. Each department has professional knowledge and high professional quality, put customers first, think about the interests of customers, actively communicate with customers and solve problems smoothly.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel chemical composition of S235J0W plate plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
