    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,
