Q345B seamless steel pipe is a low alloy series, in the low alloy material, this material is the most common. Seamless steel pipes have a wide range of uses, and can be used to process mechanical parts, transport liquids or gases, make drive bearings, and build rigid structures. Standard: GB/T8163 Equivalent Standard: EN102161, DIN1629 Material: Q345B Equivalent Material: 16Mn, St52, E355, Q355 Chemistry Composition Element C Si Mn Cr Ni S P Cu Mo % 0.20 max 0.50 max 1.70 max 0.30 max 0.50 max 0.035 max 0.035 max 0.30 max 0.10 max Mechanical Properties Tensile Strength, MPa: 470~630 Yield Strength, MPa: 345 min Elongation, %: 20 min Length The typical length of the steel pipe is 3000mm~12000mm. After negotiation with clients, other lengths can be supplied. Fixed length or multi-length ≤ 6000mm: +30/-0mm Fixed length or multi-length > 6000mm: +50/-0mm
