Product Description

The Cold-Drawn Stainless Steel Seamless Tube is manufactured through a precision cold-drawing process that enhances dimensional accuracy, surface finish, and mechanical properties. This method involves pulling a hollow billet through a die at room temperature, resulting in a uniform wall thickness, tight tolerances, and a smooth, weld-free surface. The cold-working process also increases tensile and yield strength compared to hot-rolled tubes. Ideal for high-pressure, high-precision, and critical environment applications.

Mechanical Properties

Note: Cold-drawn tubes typically exhibit higher strength than annealed tubes due to work hardening.

    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,
