The Benefit Of JIS G3445 STKM13C Cylinder Tube

The Benefit Of JIS G3445 STKM13C Cylinder Tube

STKM13C Cylinder Tube is the standard carbon steel tubes for hydraulic cylinder purpose,After seamless cold drawing, the inner diameter is processed by high-precision boring, the inner tolerance can reach H7 H8, and the surface roughness is 0.2-0.4um.

JIS STKM 13C cylinder tube and SAE 1020 aim at mechanical structural uses with similar but less working pressure than that of ST52 cylinder tube. However, such material is suitable for lathing and other further processing. ST52 and ST52.3 cylinder honed tubes are with good weld-ability, high yield strength to bear high pressure, and good impact resistance in low temperature.  If the working pressure is not high, STKM 13C honed tube is also a good choice, because the cost is relatively low than ST52.

Advantages of Our STKM13C Cylinder Tube

1.High precision tolerances;

Our STKM13C  honed tube can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension.

2.Seamless tube with high pressure resistance;We only use seamless cold drawn tubes to produce honed pipes, which means our honed tubing can work under higher pressure, thus our honed pipes are more reliable for hydraulic cylinder applications.

3.High Smooth inside surface;

The roughness of our honed pipe is Max Ra 0.4 microns ID finish (16Max Ra ID Finish).

Flexible order quantity: we accept small quantity orders, even if there is only one piece of hydraulic cylinder tubing we can produce and supply.

4.Good weld ability: The weld ability of our honed barrel tubing is very good, this is quite helpful for manufacturing the cylinders.
