Q195B Welded Pipe

Q195 is a carbon structural steel. The yield strength is 195MPA. Lower strength than Q235. The price is cheaper. Used in construction, structure, motorcycle frame, etc. The American ASTM brand is Gr.B (σs185). σs185 is the yield strength of 185MPa. Q195B Steel pipes are used widely, EMHK is specialized in Maufacturing Carbon steel pipes and Carbon steel plates, we have strict attitude in Processing steps. We can accept any types of testing, welcome your QC team to visit our production line. Pls donot hesitate to contact us if you are interested in Carbon steel pipes.

Q represents the yield limit of this material, and the latter 235 refers to the yield value of this material, which is around 235MPa. The combined version will decrease its yield value as the thickness of the material weight increases. Due to the moderate carbon content, the overall performance is better, the strength, plasticity and welding properties are better matched, and the use is the most extensive.

Q195 is used to manufacture anchor bolts, ploughshares, chimneys, roof panels, rivets, low-carbon steel wires, thin plates, welded pipes, tie rods, hooks, brackets, welded structures, etc. Rolled sheet and wire rod.

Cold and hot rolled thin steel plates and galvanized, tinned and plastic composite thin steel plates made from them are widely used in roof panels, decorative panels, general dust removal pipes, packaging containers, iron drums, instrument cases, switch boxes, and protection Covers, train cars, etc. Wire rods are mostly cold drawn into low-carbon steel wire or galvanized into galvanized low-carbon steel wire, which is used for binding, tensioning and fixing, or used as wire mesh, rivets, etc.
