Creep of low-activated Fe-12Cr-20Mn-1W austenitic corrosion-resisting steel

  • 26 Accesses


1. Creep resistance of the Fe-12Cr-20Mn-1W steel, containing 0.1-0.26 wt. % C and also small additions of Ti, B, and P in the range 823–973 K is similar to the creep resistance of the Fe-Cr-NI steels of the 304 type, 800 alloy, and also the Fe-Cr-Mn-Ni steel of the ÉP838 type.

2. An increase of the carbon content in the range 0.1–0.26 wt. % in the Fe-12Cr-20Mn-1W alloys slightly reduces the minimum creep rate 873 K and does not effect this parameter at 973 K.

3. The efficiency of the effect of carbon on the minimum creep rate of the Fe-12Cr-20Mn-1W steels is evidently lower than the 800 alloy.
