S690QL material properties vs s355jr steel material

After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, S690QL material properties tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of S690QL material properties steel and 542,000 tons of steel.

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

ASME SA537 pressure vessel uses heat-treated carbon-manganese-silicon steel plate.
The steel plates supplied by this standard are divided into three categories, namely SA537Gr1, SA537Gr2, and SA537Gr3. The maximum thickness of steel plates corresponding to these three grades is limited to: SA537Gr1 is not more than 100mm;
The thickness of SA537Gr2 does not exceed 150mm;
The thickness of SA537Gr3 does not exceed 150mm.
