Hastelloy C276 Nickel Alloy Powder
Nickel & Superalloy Powders · Metal Additive Manufacturing Powder
Hastelloy C276 (UNS N10276) is a nickel-molybdenum-chromium alloy with exceptional resistance to aggressive chemical environments: oxidizing and reducing acids, chlorides and seawater. It is the alloy of choice for AM parts in chemical processing, pollution control and flue-gas desulfurization where stainless steels fail. As-built LPBF C276 typically reaches 730 MPa UTS and 447 MPa YS with 42% elongation; solid-solution strengthening means simple stress relief suffices after printing. Gas-atomized powder in 15-53 µm is the common cut. Buyers should verify molybdenum (15-17%), chromium (14.5-16.5%) and tungsten (3-4.5%) on the mill certificate, as these elements drive the alloy's corrosion performance.

Frequently Asked Questions
How much does Hastelloy C276 powder cost?
C276 powder typically quotes $120-220 per kg given its high molybdenum content. Verified suppliers on this page respond with current quotes within 24 hours.
What environments is printed C276 best for?
Hot sulfuric and hydrochloric acid service, chlorinated media, flue-gas scrubbers and seawater. It resists both oxidizing and reducing corrosion where 316L and even 625 fall short.
Does C276 need heat treatment after printing?
A stress relief at 870-1,000°C is normally sufficient; C276 is solid-solution strengthened, so no precipitation ageing is required.
Which particle size is standard?
15-53 µm for LPBF is most common; coarser cuts for DED. Specify your application so suppliers match the cut.
How do I verify C276 powder chemistry?
Request a mill certificate per ASTM B575 with Mo, Cr, W and Fe within specification, plus particle-size distribution and oxygen content.
