Detail Information

Introduce:

This kind of steel tube is through cold drawn process with special profile mould by seamless steel tubes or welded steel tube.

Application:

Shaped seamless steel tubes are widely used in various structural parts, tools and mechanical parts. Compared with round tubes, shaped tubes generally have larger moments of inertia and section modulus, and have greater resistance to bending and torsion, which can greatly reduce the structural weight and save steel.

Steel grade:

ASTM: 1020, 1026, 1045

JIS: S20C, S45C, STKM 11A, STKM 16A, STKM 17A

EN: 1.1151, 1.0503, 1.0580, 1.0308, 1.0408

DIN:ST35, ST45, ST52

BS:E235, E275, E355

Delivery condition:

Shape:Round, square, rectangular, triangle, hexagonal, oval and other special sections.

 

Outside Diameter range: 8mm-114mm

Tolerance of OD:+/-0.20mm

Wall Thickness range: 1mm-25mm

Tolerance of WT: +/-0.12mm

Straightness: ≤2.0mm/m

 

Special shaped tubes process:Steel bar→ punched→ heat treatment→ acid pickling→ cold drawn→ stress relieved→ dimension inspection→ package

 

Delivery condition:Cold drawn only, Normalized, Stress relieved

 

Surface condition: Bright, Smooth, Black

 

Test: MTC is issued in accordance with EN 10204. Chemical test, mechanical property, tension test etc.
