We will uphold the support of all sectors of society, actively provide users with steel plate specification grade S690QL high-quality and efficient services, work together for win-win, and create a better tomorrow!

The company is a professional manufacture and stock keeper of Q245R boiler steel plate, Q345R boiler plate, 15CrMoR boiler steel plate, SA516 Gr 70 boiler steel plate, 16MnDR boiler steel plate, steel plate specification grade S690QL, and so on steel materials. The steel product can be produced according to GB, ASTM, ASME, JIS, DIN and EN standards. The thickness range of the pressure vessel and boiler steel plates is 3mm - 180mm. The pressure vessel and boiler steel products are widely used in petroleum, chemical, paper, power, nuclear power, heat exchanger, condenser, food and beverage, medicine and other industries or engineering.

steel plate specification grade S690QL, low alloy high strength steel has good atmospheric corrosion resistance and is widely used in engineering structure construction. Most of the engineering structures are used in the atmosphere or marine environment. A small amount of Cu, Ni, Cr, P and other elements are added to the low alloy high strength steel, which effectively improves the corrosion resistance of the engineering structure in the atmosphere, sea water and soil. If 0.2% - 0.5% copper, 0.05% - 0.1% phosphorus and aluminum are added, the corrosion resistance of steel can be improved obviously, and the effect of adding copper and phosphorus at the same time is the best.

Rolling steel is the process of pressing to change the shape of the ingot and billet between the rotating rolls. The so-called steel rolling process is a combination of a series of steel rolling processes. The entire rolling production process is always composed of the following steel plate specification grade S690QL basic processes: ① billet preparation:Including the cleaning of surface defects, the removal of surface scale and the pre-heat treatment of billets. ② billet heating ③ steel rolling: it is the core of the entire rolling production process. ④ Finishing.

"ASTM A516 Grade 70 plate is a boiler / pressure vessel quality of steel plate for use in low to moderate services. It has improved notch toughness. steel plate specification grade S690QL, A516 Grade 70 steel plates can be produced with thick up to 200mm.For boiler steel plate A516 Grade 70, the yield strength shall be above 260 Mpa, tensile strength from 485 Mpa to 620 Mpa.A516 Garde70 steel plate is equivalent to the P355GH and 490B grades. "
