Product Description

The Industrial Grade Welded Stainless Steel Pipe is manufactured from high-quality austenitic stainless steel coils, formed into a cylindrical shape, and longitudinally welded using advanced automatic welding processes. Designed to meet the demanding requirements of industrial applications, this pipe offers reliable corrosion resistance, consistent mechanical properties, and cost-effective performance. It is an excellent alternative to seamless pipe for moderate pressure and non-critical service conditions where weld integrity is verified through rigorous nondestructive testing.

    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,
