Haynes-188 GH5188 Stainless Steel Round Bar Haynes 188 Material Haynes 188 Forging Bar
Alloy® 188 is a cobalt-base austenitic alloy with excellent high temperature strength and good oxidation resistance to 2000°F (1093°C). The high chromium level coupled with small additions of lanthanum produce an extremely tenacious and protective scale. The alloy also has good sulfidation resistance and excellent metallurgical stability displayed by its good ductility after prolonged exposure to elevated temperatures.
Alloy 188 is non-magnetic. It has good high temperature strength up to 1800ºF (982˚C) and good oxidation resistance up to 2100ºF (1149˚C). This alloy performs well in continuous high temperature service and has excellent oxidation, spalling and corrosion resistance, achieved through the addition of chromium in combination with a minute amount of lanthanum. The lanthanum addition produces a tenacious, protective oxide scale at high temperatures. This alloy also maintains its ductility at cryogenic temperatures but strength levels are increased substantially.
