Marine class steel EN 10083-3 alloy steel grade 50CrMo4
Seamless steel tubes for high-pressure boilers are mainly used in pipes, headers, economizers, superheaters and heat exchangers of high-pressure boilers. The working pressure of seamless steel tubes for high-pressure boilers is generally above 9.8 MPa and the working temperature is between 450℃ and 650℃. The main grades of seamless steel tubes for high pressure boilers are 15CrMoG, 12CR2MOG, 12Cr1MoV, EN 10083-3 alloy steel grade 50CrMo4, etc.. For the seamless steel tubes used for high pressure boilers, their service environment and related properties are also different for different grades.
EN 10083-3 alloy steel grade 50CrMo4, EN 10025 E355 steel plate / sheet is suitable for general building steel. Chemical composition and mechanical properties of EN 10025 E355 steel. EN 10025 E355 steel conforms to EN 10025 standard, equivalent to DIN 17100: ST60-2, NFA: a60-2, UNI 7070: FE590 steel grade.
Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the EN 10083-3 alloy steel grade 50CrMo4 plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.
