Chemical Composition

The chemical composition of Hastelloy C-276 (UNS N10276) complies with ASTM B575, B574, and B622 standards. The extremely low carbon content (≤0.01%) distinguishes C-276 from earlier C-type alloys.

ElementContent (%)Role
Nickel (Ni)Balance (≥52%)Provides SCC resistance and austenitic stability
Chromium (Cr)14.5 – 16.5Enhances oxidation and corrosion resistance
Molybdenum (Mo)15.0 – 17.0Provides resistance to reducing acids and pitting
Tungsten (W)3.0 – 4.5Further enhances localized corrosion resistance
Iron (Fe)4.0 – 7.0Improves metallurgical stability
Cobalt (Co)≤ 2.5Residual element
Manganese (Mn)≤ 1.00Aids in hot workability
Vanadium (V)≤ 0.35Trace element
Silicon (Si)≤ 0.08Improves oxidation resistance (controlled to low level)
Carbon (C)≤ 0.01Key feature – prevents intergranular attack
Phosphorus (P)≤ 0.04Minimized to maintain ductility
Sulfur (S)≤ 0.03Controlled for hot workability

Actual mill test certificates (EN 10204 3.1) available per batch.

Comparison: Hastelloy C vs C-276
ElementHastelloy C (max %)Hastelloy C-276 (max %)
Carbon (C)0.080.01
Silicon (Si)1.000.08
Key DifferenceHigher C and SiUltra-low C + W for superior corrosion resistance

Both alloys contain nickel as a balance (minimum ~52%). C-276's extremely low carbon and silicon content eliminates intergranular precipitation after welding, making it the superior choice for welded fabrications in corrosive service.

    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,
