HASTELLOY C-276（UNSN10276） WIRE

HastelloyC276 Wire
Nickel-Chromium-Molybdenum-Tungsten Alloy for Severe Corrosive Environments

HASTELLOY C-276 wire is supplied in coils or on spools for corrosion-resistant components, wire mesh, springs, fasteners, and certain welding/overlay applications. It provides excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking in aggressive chemical environments.

As a professional Chinese nickel-based alloy manufacturer, we supply HASTELLOY C-276 wires with stable chemistry, consistent mechanical properties, and flexible dimensional customization for global industrial users.
