Alloy C-276 – Hastelloy Weldability

Back To Weldability Alloys

Hastelloy C-276 alloy can be forged, hot-upset and effect expelled. In spite of the fact that the alloy tends to work-harden, you can have it effectively spun, deep drawn, press shaped or punched. The greater part of the regular strategy for welding can be utilized, in spite of the fact that the oxyacetylene and submerged arc process are not recommended when the created thing is for use in corrosion service. Weldable by every normal strategy with the exception of that excessive heat input should be avoided. Hastelloy C-276 can be utilized as a part of the "as-welded" condition without further heat treatment for most corrosive applications.

Applications
