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

采用热压缩和热拉伸试验方法,对00Cr22Ni5Mo3N双相不锈钢的高温变形抗力、高温塑性以及在高温变形时的奥氏体相的数量进行了研究。试验结果表明,00Cr22Ni5Mo3N双相不锈钢的高温变形抗力和高温塑性较0Cr18Ni10Ti奥氏体不锈钢低,在1100～1250℃变形时,钢中奥氏体相的数量可以控制在适合热加工的范围,使钢具有较好的热加工性能。

With employment of the thermocompression test and thermal tensile tes t, the hot workability of the 00Cr22Ni5Mo3N dual phase stainless steel is studie d, focusing on the hi-temperature deformation-resistance, hi-temperature plasti city and the quantity of austenitic phases during deformation in high temperatur e. The result shows that the hi-temperature deformation-resistance and hi-temper ature 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 ex tent for the hot work so as to ensure better hot workability of the said dual ph ase stainless steel.
