Q345B material is a low-carbon alloy steel (c <0.20%), with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345R steel is a special plate for pressure vessels with a yield strength of 345MPa. It has good comprehensive mechanical properties and technological performance. In addition to the tensile strength and elongation requirements higher than Q345 (16Mn) steel, Q345R is also required to ensure impact toughness.
The chemical composition of Q345D seamless steel pipe is as follows: C ≤ 0.18, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S≤ 0.025, Nb ≤ 0.07, V ≤ 0.15, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.012, Mo ≤ 0.10, Al ≥ 0.015. RB hull structural rolled steel, Q345D seamless steel pipe has good comprehensive mechanical properties, low temperature impact toughness, corrosion resistance, cold stamping, machinability and weldability. Q345D seamless steel pipe is widely used in welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, etc..
LSAW Pipe to Peru. In the beginning of 2014, Peru government released an international tender for one of the hydroelectric power plant. Finally they chose us as the contractor, we purchased the steel plate and then fabricate the RB hull structural rolled steel steel plate into steel pipe, and then make the corrosion protect on the surface, we also supply the fitting with our steel plate, the total value of this order is about 2 million USD.
The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide RB hull structural rolled steel cutting, bending and so on processing to change plate size and shape according to your requirements. Welcome to consult us about RB hull structural rolled steel ASTM A204 grade B properties, SA 516 gr 70 temperature range, ASTM A285 grade C chemical composition, boiler steel price and so on questions and ask for offer.
