Abstract

The critical transformation temperature Ac1 and Ac3 of steel 2.25CrlMo0.25V steel under different heat treatment process conditions are studied by thermal expansion method. The results show that the critical transformation temperature of the steel annealed is 797.1 ℃ and 886.2 ℃, the critical transformation [KG*4]temperature [KG*4]of [KG*4]the [KG*4]steel [KG*4]quenched [KG*4]is 801.3 ℃ and 891.4 ℃ and the critical transformation temperature of the steel quenched and tempered is 809.2 ℃ and 898.7 ℃. Different structures affect the critical transformation temperature. So the influence of heat-treating process on the performance and structure should be considered.
