HASTELLOY C-276（UNSN10276） Sheet / Plate
Nickel-Chromium-Molybdenum-Tungsten Alloy for Severe Corrosive Environments
HASTELLOY C-276 is a nickel-chromium-molybdenum alloy with tungsten designed for outstanding corrosion resistance in a wide range of aggressive chemical environments. With extremely low carbon and silicon, it helps maintain corrosion resistance in as-welded structures and provides excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking.
As a professional Chinese nickel-based alloy manufacturer, we supply HASTELLOY C-276 sheets and plates with stable chemistry, consistent mechanical properties, and flexible dimensional customization for global industrial users.
Typical supply range (custom sizes and tolerances available upon request):
Item | Range / Options | Notes |
Thickness | 0.5 – 50 mm | Sheet typically ≤ 6 mm; Plate typically ≥ 6 mm (project-defined). |
Width | Up to 2000 mm | Slitting service available; define tolerance if critical. |
Length | Up to 6000 mm | Cut-to-length (shearing), waterjet/plasma by agreement. |
Surface finish | 2B / No.1 / BA / Polished | PVC protective film optional for surface-critical parts. |
Edge | Mill edge / Slit edge | Deburring / edge conditioning available. |
Flatness / tolerance | Per ASTM/EN or as agreed | Define flatness for heat-exchanger plates and welded assemblies. |
Delivery condition | Solution annealed (standard) | Pickled/bright annealed depending on thickness/finish. |
