Product Description

UNS N08810 is a nickel-iron-chromium alloy specifically designed for high-temperature service requiring good creep and rupture strength above 600°C (1112°F). It is a controlled chemistry version of UNS N08800 (Alloy 800), with tighter limits on carbon (0.05-0.10%) and a coarse grain size requirement (ASTM 5 or coarser) to optimize high-temperature properties.

The alloy maintains an austenitic structure and offers excellent oxidation and carburization resistance, as well as good corrosion resistance in high-temperature environments. UNS N08810 is particularly valued for its superior creep-rupture strength compared to standard 800, making it the preferred choice for petrochemical furnaces, heat treating equipment, and power generation components operating in the 600-900°C range.

    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,
