Hastelloy® Alloy Plate (C-276, C-22, B-2, etc.)
Engineered for industries battling highly corrosive, oxidizing, and high-temperature environments, Hastelloy® alloy plates deliver unmatched resistance to acids, chlorides, and pitting/crevice corrosion. With nickel-molybdenum-chromium matrices (e.g., C-276: Ni-57%, Mo-16%, Cr-16%), these plates excel in applications where stainless steel fails. Certified to ASTM B575, ASME SB575, and NACE MR0175, they outperform competitors with 10x longer service life in HCl, H₂SO₄, and Cl⁻-rich media, ensuring reliability in chemical, oil & gas, and nuclear sectors.
