Experimental Research on Hot Workability of 00Cr22Ni5Mo3N Dual Phase Stainless Steel

With employment of the thermocompression test and thermal tensile test, the hot workability of the 00Cr22Ni5Mo3N dual phase stainless steel is studied, focusing on the hi-temperature deformation-resistance, hi-temperature plasti city and the quantity of austenitic phases during deformation in high temperature. The result shows that the hi-temperature deformation-resistance and hi-temperature plasticity of the said steel is lower than those of the 0Cr18Ni10Ti austen ite stainless steel, and that during deformation in the temperature range of 1,1 00~1,250 ℃, the quantity of austenitic phases can be controlled to a proper extent for the hot work so as to ensure better hot workability of the said dual phase stainless steel.
