q345b st52 cold drawn honed cylinder Steel tube carbon pipe

1.Seamless steel tube and carbon tube

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

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

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. SRB&Honed steel tube

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.
