Product Description

UNS N06625 is a nickel-chromium-molybdenum alloy with outstanding corrosion resistance and high strength over a broad temperature range from cryogenic to 980°C (1800°F). The addition of niobium (columbium) and tantalum provides exceptional resistance to pitting, crevice corrosion, and chloride ion stress-corrosion cracking.

Unlike many high-temperature alloys, UNS N06625 does not rely on precipitation hardening for strength. Instead, it derives its high tensile and creep-rupture strength from the solid solution strengthening effect of molybdenum and niobium. This gives the alloy excellent weldability without the need for post-weld heat treatment, making it ideal for fabricated components in aggressive environments.

    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,
