Certificates and documentation
Alloy 617 can be supplied with a material certificate to EN 10204, depending on producer, dimension and the requirements specified for the delivery. On stainless, the analysis and the delivery condition are what the certificate shows. If a specific test or an ageing/hardening condition is to be documented, it must be specified before we order. EN 10204 3.1 can be supplied on a wide range of our materials.
