High Precision H8 H9 Hydraulic Cylinder Cold Rolled Pipe Tube

High Precision H8 H9 Hydraulic Cylinder Cold Rolled Pipe Tube

1.Seamless steel tube and carbon tube, seamless pipe

Widely used in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT, ST52, CK45 and AISI 1020. We can also offer as customized seamless steel tube.

ld drawn steel tube/cold rolled steel tube, cold drawn pipe, cold rolled pipe, cold drawn tube, cold rolled tube

Grade: 20# 45# 16Mn 25Mn 27SiMn E355 ST52 STKM11A STKM13A ST52 S45C CK45

Standard: GB/T8713 GB/T3639 DIN2391 EN10305 ASTMA519

Range: 30-300mm

Length: 11m(max)

The cold process can change the thickness of tube to meet client's request and offer better mechanical property.

3. Honed steel tube&SRB steel pipe, honed tube, honed steel pipe

ID Tolerance: H8 H9

ID Roughness: RA0.4micron(max)

Length: 6m(max)

Inner roughness: Ra0.2-0.8um

Straightness: 1:1000 or customized

This process can improve the roughness of the inner tube to 0.2-0.8um and make inside tube more smooth which can be used for cylinder directly.
