Nickel-molybdenum-chromium superalloys engineered for outstanding resistance to both oxidising and reducing acids, supplied across C-276, C-22, B-2, B-3, G-30 & X with full Mill Test Certification.
Hastelloy is a family of nickel-molybdenum-chromium superalloys developed for the harshest chemical processing environments. Grade C-276 offers exceptional resistance to a wide range of chemical process conditions, while B-2 and B-3 excel in hydrochloric and other reducing acids where molybdenum-only compositions perform best.
Every batch is supplied with complete material traceability and Mill Test Certificates across our full range of tubes, pipes, sheets, plates, bars, rods, wire and flanges.
Stocked across the full Hastelloy family, each manufactured to its respective ASTM / ASME standard.
