Amperprint 0233 – Haynes 282 
3d Printing

Material & Process Capability

Amperprint® 0233 HAYNES® 282® powder is produced by Höganäs under license from Haynes International. Inc. It is a vacuum induction melted, argon gas atomized, spherical powder for additive manufacturing. Velo3D has qualified this powder, produced by Höganäs AB, a world leader in metal powder production, under license from Haynes International, for use in the Sapphire® family of printers. The Velo3D end-to-end metal AM solution uniquely enables companies to build the parts they need without compromising design or quality – resulting in complex parts higher in performance than casting or other methods.

This alloy is a gamma-prime strengthened nickel-chromium-cobalt superalloy for high temperature applications and shows a good balance of creep strength at high temperatures, thermal stability, weldability, and fabricability.

General Process

In addition to its strength, the alloy is characterized by its superb fatigue, creep, and corrosion resistance under extreme conditions; it is ideal for high temperature applications such as gas turbine and power/process industry parts.

This data sheet specifies the expected mechanical properties and characteristics of this alloy when manufactured on a Velo3D Sapphire System. All data is based on parts built using Velo3D standard 50 μm layer thickness parameters, using Amperprint 0233 HAYNES 282. Parts built with this alloy on a Sapphire System can be heat treated like those manufactured by other methods. Haynes 282 is a registered trademark of Haynes International, Inc.
