Product Description

En10305-1 E355+SR cold rolled Seamless steel tube

 

 

 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.

 

The difference between honed pipe and seamless steel pipe

1, the main feature of seamless steel pipe is welded joints, can withstand greater pressure. The product can be very rough as cast or cold parts.

2,honed tube is the product in recent years, mainly the hole, the outer wall size has strict tolerances and roughness.

our tubes

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.
