Corrosion Resistant Alloy C-276 Bar

Alloy C-276 is frequently used in many industries, including chemical and petrochemical processing, oil and gas, power generation, pharmaceutical, pulp and paper production and waste water treatment. End use applications include stack liners, ducts, dampers, scrubbers, stack gas reheaters, heat exchangers, reaction vessels, evaporators, transfer piping and many other highly corrosive applications.

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.
