Alloy 22 Bar - Corrosion Materials

Corrosion Resistant Alloy 22 Bar

Alloy 22 is a fully austenitic, nickel-chromium-molybdenum-tungsten alloy with better overall corrosion resistance compared to other nickel-chromium-molybdenum alloys, including alloy C-276, alloy C4 and alloy 625. The high chromium content provides good resistance to oxidizing media while the molybdenum and tungsten content gives good resistance to reducing media. This combination of corrosion resistance makes alloy 22 particularly useful in applications where mixed acids are present.

You can purchase bar in standard lengths or we offer cut-to-length services with our bar processing equipment. If you require further processing, we offer machining services including: turning, grinding, polishing, milling, drilling, tapping, threading and boring.
