S500QL structural alloy prices continue to rise

Vanadium is a weak deoxidizer. Adding vanadium into S500QL structural alloy steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

Our quality control department will do inspection for details of the steel materials S500QL structural alloy before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.

The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of S500QL structural alloy structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.

We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product S500QL structural alloy annual capacity is 200 thousand tons.
