Attentions in machining S690QL ASTM equivalent

In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like S690QL ASTM equivalent, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.

Grades S690QL ASTM equivalent, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance. C, D, E grade steel has good low temperature toughness. Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts.

The company specializes in hot rolled plates producing, steel plate processing, steel plates cutting, carbon steel plate weldding and exporting of wide and thick steel plates. BBN company has high-quality CNC S690QL ASTM equivalent steel plate cutting processing equipment, professional technical personnel, and supporting marketing and after-sales service system.
