Imported Hastelloy C22 Precision StripFor High-Purity Regulator Diaphragms
Explore corrosion-resistance requirements for high-purity pressure-regulator diaphragms and the supply of imported Hastelloy C22 precision strip.
01
High-Purity Regulator Diaphragm Requirements
Regulator diaphragms respond to pressure differentials and require compatibility with corrosive gases, repeated flexing, clean surfaces and reliable sealing interfaces.
02
How Hastelloy C22 Fits
Hastelloy C22 (UNS N06022) is a nickel-chromium-molybdenum-tungsten alloy with outstanding resistance to pitting, crevice and stress corrosion in oxidizing and reducing media, including chloride-containing environments. Its low carbon and silicon levels help maintain corrosion resistance in welded heat-affected regions. We offer diaphragm-grade precision strip in several mechanical conditions with continuous mirror-polished finishing.
