HAYNES® HR-235® alloy is a fabricable, nickel-chromium-molybdenum-copper alloy with outstanding resistance to metal dusting. Our company has invested in a multi-year effort to achieve the ASME Code Case by conducting extensive testing of multiple heats of wrought product forms of HR-235® alloy. This Code Case will allow HR-235® alloy to be used at temperatures up to 1600°F (870°C) in product forms including plate, sheet, strip, bar, fittings, seamless pipe/tubing, and welded pipe/tubing. HR-235® alloy filler wire is also available for welded construction.
