Grade Compliance
C22 Material for Lower Punch Supplier | Hastelloy C-22 N06022 Ground Round Bar carries the recorded grade references UNS (USA) N06022, DIN / EN 2.4602 / NiCr21Mo14W, Haynes Trademark HASTELLOY® C-22®, GB HASTELLOY® C-22®, and Common Names Alloy 22. These references give engineering and procurement teams a starting point for checking material identity, equivalent designations, and documentation requirements. A grade reference should always be read together with its applicable standard, product form, dimensional range, delivery condition, heat treatment, testing requirements, and revision level. Equivalent designations are not automatically interchangeable in every service, so the governing project specification remains controlling. Before order placement, confirm the required standard and certificate format, including chemical, mechanical, visual, dimensional, and any special testing requirements. Vertex Alloy can help compare the requested designation with the available product record and identify details that need confirmation from the producing mill.
