Carbon structural steel Q195 is used to transport low pressure fluids

〣Introduction to carbon structural Steel Q195
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).

〣Production technology
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.

Minimum Order: 1 tons
