Product Description

Cold drawn stainless steel round pipe is manufactured through a multi-stage drawing process that pulls a hot-rolled or extruded tube through a die at room temperature. This cold working process produces a pipe with superior dimensional accuracy, smoother surface finish, enhanced mechanical properties, and tighter wall thickness tolerances compared to hot finished alternatives.

The cold drawing process work-hardens the material, increasing tensile and yield strength while maintaining excellent uniformity. This makes cold-drawn pipes the preferred choice for precision applications such as hydraulic lines, instrumentation tubing, heat exchanger tubes, and high-pressure fluid transfer systems.

Dimensional Tolerances (Cold Drawn)

Cold drawing achieves significantly tighter tolerances than hot finished products:

OD Tolerances (ASTM A269)
OD Range (mm) Tolerance (mm) ISO Class
3 – 10 ±0.05 h9
10 – 25 ±0.05 – ±0.08 h9
25 – 40 ±0.08 – ±0.10 h9/h8
40 – 60 ±0.10 – ±0.12 h9
60 – 100 ±0.12 – ±0.15 h9/h11
100 – 150 ±0.15 – ±0.20 h11
Wall Thickness Tolerances
Wall Thickness (mm) Tolerance (%)
0.5 – 2.0 ±10%
2.0 – 5.0 ±8%
5.0 – 15.0 ±8%
Length Tolerances
Length Type Tolerance
Random Length 3m – 12m (no specific cut)
Fixed Length +3mm / -0mm
Coiled Tube Continuous lengths up to 500m
Straightness
Condition Straightness
Standard ≤0.8mm per meter
Precision ≤0.5mm per meter
Ultra Precision ≤0.3mm per meter

Surface Roughness (Ra):

  • Standard cold drawn: ≤1.6μm
  • Polished: ≤0.4μm
  • Bright annealed: ≤0.8μm
Cold Drawing Process

Cold Drawing Methods:

Method Description Best For
Sunk Drawing No internal support Small OD reductions, general purpose
Rod Drawing Mandrel supports ID Precise ID and wall thickness
Plug Drawing Floating or fixed plug Thin walls, precision ID
Tube Reducing Rotary forging process Large reductions, heavy walls

Why Multiple Passes?

  • Each pass reduces OD and wall thickness by 15-30%
  • Multiple passes allow for a greater total reduction
  • Intermediate annealing restores ductility between passes
  • Final pass determines final dimensions and surface finish

    Precision 301 304 316 430 Cold Rolled Stainless Steel Strip 2B BA No.4 Finish
    Precision cold rolled stainless steel strip is a narrow, thin-gauge stainless steel product manufactured to significantly tighter thickness and width tolerances than standard cold-rolled sheet. Unlike standard sheet (typically 1000mm or 1219mm wide), precision strip is produced in narrow widths — usually less than 600mm — and thin gauges from 0.05mm up to 3.0mm. The key differentiator is the tolerance : the precision strip holds thickness variations to as low as ±0.005mm,
