Product Description

product name	Cold Drawn Special-shaped carbon Steel Tube
Matrial	10# 20# Grade A,B,C,D Carbon Steel
Size	OD: 12-1200mm WT: 1-22mm Length: Customer's Requirement
length	5.8~6m

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.

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
