The strict quality control for JIS G3106 SM570 low alloy steel plates

JIS G3106 SM570 low alloy steel plates need cooling after rolling, straightening, shearing, or tag, flame cutting, grinding defects, surface quality and dimension inspection, sampling inspection, printing marks, collection, storage, etc.

Some JIS G3106 SM570 steel plates also require heat treatment and pickling according to process requirement or user requirement.

In order to ensure the flatness of JIS G3106 SM570 low alloy steel plates, in addition to various common measures, SM570 steel plate with thickness less than 40mm needs thermal straightening.

According to the quality requirements of JIS G3106 SM570 low alloy steel plate, ultrasonic testing technology is adopted to ensure the mechanical properties of SM570 steel plate. BBN steel also controls the good shape of SM570 steel plate.

Sand spraying and shop primer are good measures to prevent steel plate from rusting during transportation. The size and shape of JIS G3106 SM570 low alloy steel plate is mainly determined by manual operation. The marking process has been mechanized and controlled by computers.
