S690QL equivalent grade welding

ASTM A633 standard covers four grades A, C, D, and E normalized high-strength low-alloy structural steel plates for welded, riveted, or bolted construction. S690QL equivalent, A633 Grade A structural steel provides a minimum yield point of 42 ksi [290 MPa] in thicknesses through 4 in. [100 mm], inclusive. Grades C and D provide a minimum yield point of 50 ksi [345 MPa] in thicknesses up to 2.50 in. [65 mm], inclusive and 46.0 ksi [315 MPa] in thicknesses over 2.50 in. to 4.0 in. [65 to 100 mm], inclusive.

Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional S690QL equivalent production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of S690QL equivalent leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

We have a lot of advantages for S690QL equivalent steel plate processing. First, we have huge steel plate stock. That not only saves material preparation time, but also saves much transportation cost. Second, we have professional technical team, who can design drawing according to client requirements quickly. Or if clients have drawing, we can communicate and make it clear soon. Third, we have built special steel processing center. The professional and experienced work will make you more satisfied and at ease.
