The classic nickel–chromium alloy for caustic, high-temperature chlorine and furnace hardware.
600 is a nickel–chromium alloy with good mechanical strength and excellent resistance to oxidising media at high temperature. It is particularly associated with caustic service, where it resists stress-corrosion cracking that destroys stainless steels, and with dry chlorine and hydrogen chloride at elevated temperature.
It also has good resistance to carburising and nitriding atmospheres, which is why it appears in furnace fixtures, retorts and heat-treatment equipment.

The default alloy for mixed acids, chlorides and wet chlorine — and the grade most often specified when no one is sure what the stream will do.
