Product Description

Bright annealed stainless steel tube is manufactured through a specialized heat treatment process performed in a controlled atmosphere furnace (hydrogen or vacuum). This process produces a clean, oxide-free, bright surface without the need for pickling or post-treatment. The result is a tube with excellent surface finish, improved corrosion resistance, and superior mechanical properties.

Key Features:
  • Oxide-free, bright surface finish (Ra ≤ 0.4μm)
  • No pickling required – environmentally friendly
  • Improved corrosion resistance due to passive layer formation
  • Uniform microstructure and mechanical properties
  • Excellent for bending, flaring, and welding
  • Available in seamless or welded construction

    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,
