How do the characteristics of inconel buttweld fittings affected by cold or hot working?

The impact of cold or hot working on inconel buttweld fittings depends on the specific alloy grade and extent of the working process. Generally, the cold working process improves the strength and surface finish of the fittings. However, it reduces the ductility and impact strength.

On the other hand, hot working improves ductility and induces recrystallization to relieve residual stress and refine the grain structure. It also reduces the tensile strength of the fittings.

We stock inconel buttweld fittings from 1/2′′ to 10′′ (seamless) and 1/2′′ to 48′′ (welded) at the most competitive prices as per ANSI/ASME B16.9 , Ordering online will save you money.
