(1)Seamless steel tube, carbon steel 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.

(2)cold drawn steel tube/cold rolled steel tube, cold drawn pipe

Grade: 20#  45#  16Mn  25Mn  27SiMn  E355  ST52 STKM11A STKM13A SAE4130 4140

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

ID Tolerance: H8  H9 or as client's request

ID Roughness: RA0.4micron(max)

Length: 6m(max)

Inner roughness: Ra0.2-0.8um
