Standard size Q690C carbon steel plate sheet

ASTM A335 P11, P22, P91 pipes are commonly used in power plants and chemical-petrochemical industry, while P9 and P5 pipes are mainly used in petroleum refineries. BBN steel company supplies ASTM A335 Cr-Mo alloy steel seamless pipes sized from 1/2″ to 24″ranging in wall thickness from SCH20 to XXS or even thicker. The Q690C carbon steel plate sheet specification covers nominal wall and minimum wall chrome-molybdenum( also known as Cr-Mo, or Cr-Moly) alloy steel pipe intended for high-temperature application.

High strength steel is a kind of steel often used in engineering construction. With the improvement of technical level, the research and development of high strength steel in China has made remarkable achievements. The application of high strength steel Q690C carbon steel plate sheet in the construction field can reduce the steel consumption and building volume, and improve the building weight. That is one of the important reason why the high strength steel is so warmly welcomed nowadays.

How to distinguish between hot rolled and cold rolled process?The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, Q690C carbon steel plate sheet, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.
