INCONEL® alloy 690 is a high chromium content version of INCONEL® alloy 600 with excellent resistance to many oxidising acids and salts and some resistance to sulphidation at elevated temperatures. The resistance in Nitric acid plus hydrofluoric acid mixtures lends itself to pickle shop duties. However the superior stress cracking resistance of the alloy caused it to supercede INCONEL® alloy 600 in steam
The alloy can be readily forged in the temperature range of 2250 F to 1900 F.
