Hastelloy C-2000 (UNS N06200 / W.Nr. 2.4675) round bar and rod are supplied for broad corrosion resistance across oxidizing and reducing media, with a controlled copper addition that supports performance in sulfuric-acid environments. Sasa Alloy reviews dimensions, condition, testing and documentation against the purchase order before quotation.
Final material suitability depends on the process medium, concentration, temperature, stress, fabrication route and governing design code.
