Product Description

DIN2391CK45 lowest price cold rolled seamless steel pipe

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.

The characteristics of the honed tube

1. smaller diameter.

2. High precision can be done in small quantities

3. High-precision finished products, the surface quality is good.

4. Steel pipe cross-sectional area is more complex.

5. Steel pipe performance is superior, metal is relatively dense

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
