Stock S355K2 carbon steel material hot rolled structural

S355K2 carbon steel material,ASTM A633 material is particularly suited for service at low ambient temperatures and higher where notch toughness better than that expected in as-rolled material of a comparable strength level is desired. S355K2 carbon steel material, A633 Grade E high-strength low-alloy structural steel provides a minimum yield point of 60 ksi [415 MPa] in thicknesses up to 40 in [100 mm], inclusive and 55 ksi [380 MPa] in thicknesses over 4 in to 6 in [100 to 150 mm], inclusive,S355K2 carbon steel material.The company's main business: ship plate, low alloy plate, automobile steel, high-strength plate, pipeline steel, boiler steel plate, weathering plate, wear-resistant plate, bridge plate, pressure vessel plate, steel plate, steel processing, etc. The company takes the implementation of high-end, high-quality, deep processing, strengthening the main business, diversified operation, group operation, enterprise transformation and upgrading as its development strategy, and makes all efforts to be your professional steel supplier and partner.S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.Alloy steel plate: The primary purpose of adding alloy elements to steel is to improve the hardenability of the steel, and it is easy to obtain martensite during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are smaller, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, ,S355K2 carbon steel material.The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.S355K2 carbon steel material
