Honed tube features
1, improved the surface roughness, roughness can be basically Ra ≤ 0.08 micro.
2, correction roundness, oval can be ≤ 0.01mm.
3. improved the surface hardness, so that the deformation of the force to eliminate, improve the hardness HV ≥ 4 °
4, after processing residual stress layer, improve fatigue strength increased by 30%.
5, improved with the quality, reduce wear and tear to extend the life of parts, but the parts of the processing costs instead.
we can provide such pipes:
1.Seamless steel tube and carbon tube
Widely used in oil,drilling, gas, 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.precision steel tubes
cold drawn steel tube/cold rolled steel pipe
Grade: 20#45#16Mn25Mn Q345 27SiMnE355ST52 STKM13A STKM13C
Standard: GB/T8713GB/T3639DIN2391EN10305ASTMA519
Range: 30-300mm
Length: 11m(max)
The cold process can remove the oxide layer outside to improve surface and offer better mechanical property, also can change ID,OD,WT to meet every client request.
3. Honed steel tube&SRB steel pipe
ID Tolerance: H8H9 or as client's request
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 tube for cylinder using directly.
