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 A516 Gr 70 pressure vessel steel sheet 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.
Sprin steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. A516 Gr 70 pressure vessel steel sheet, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. The smelting of A516 Gr 70 pressure vessel steel sheet, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to guarantee high purity. The content of sulfur, phosphorus, oxygen and nitrogen of spring steel should be low, and the uniformity and stability of spring steel should be good.
