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 A514 Gr E alloy steel plate 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.
Q235 is a kind of carbon steel. A514 Gr E alloy steel plate, Q235 steel is widely used in steel structure construction because of its good toughness, good plasticity, certain elongation, good welding performance and heating performance. Q235A steel plate contains C ≤ 0.22%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.050, P ≤ 0.045. Q235B steel plate contains C ≤ 0.20%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.045, P ≤ 0.045. Q235C steel plate contains C ≤ 0.17%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.040, P ≤ 0.040. Q235D steel plate contains C ≤ 0.17%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.035, P ≤ 0.035.
