Ductility testing of slicklines in theory

Sandvik wire products acquired by Zapp AG

Sandvik’s round and flat wire business has been acquired by Zapp AG from August 31, 2018. Over the coming months Zapp will be integrating the Sandvik portfolio, to provide a smooth transition for customers. During the integration period, the full line of Sandvik wire products will continue to be accessible on this website, or via the Zapp website.

Please note: divestment of round and flat wire products does not include EXERA fine wire and medical wire components manufactured by Sandvik Palm Coast.

Wrap testing is the recommended method for testing ductility in stainless and nickel alloy wirelines. Torsion testing is recommended for testing ductility in carbon steel wirelines. The reason for differentiating the two steel types is that carbon steel and stainless steel differ greatly in structure.

The isotropic (meaning ductile in all directions) structure of carbon steel makes torsion testing the ideal method for that product.

Anisotropic (meaning ductile in only one direction) stainless steels are best served by wrap testing, which exerts surface pressure only in the more suitable longitudinal direction.
