Carbon structural steel Q195 is used to transport low pressure fluids

by Zhi shang Metallic material

This kind of steel is generally smelted by converter or open furnace, and its main raw material is molten iron and scrap steel. The content of sulfur and phosphorus in steel is higher than that of high-quality carbon structural steel, with sulfur ≤0.050% and phosphorus ≤0.045%. The content of other alloying elements, such as chromium, nickel and copper, brought into the steel by the raw material generally does not exceed 0.30%.International standard ISO: HR2(σs195).

Q195 steel pipe is carbon structural steel, production process: arc welded pipe resistance welded pipe gas welded pipe furnace welded pipe.

Q195 weld pipe to transfer low pressure fluid. General welding pipe Q195A, Q215A, Q235A steel manufacturing. It can also be made of other mild steels which are easy to weld. Water pressure, bending, flattening and other experiments should be carried out on the steel pipe, which has certain requirements on the surface quality. Usually, the delivery length is 4-10m, and the delivery length is usually fixed (or multiple) feet. The specification of the welded pipe is expressed by the nominal diameter (mm or inch). The nominal diameter is different from the actual diameter. The welded pipe has two kinds of ordinary steel pipe and thickened steel pipe according to the specified wall thickness, and the steel pipe has two kinds of thread and no thread according to the form of the pipe end.

Q195 is a carbon structural steel. Yield strength 195MPA. Lower strength than Q235. The price is cheaper. Used in construction, structure, motorcycle price, etc. The ASTM brand is Gr.B(σs185). σs185 is a yield strength of 185MPa.
