日本特公昭61—055571B。在1100～1300℃对含Cr16～26％和Ni12～22％的奥氏体不锈钢扁坯进行扩散退火处理。在表面温度降至950℃后开始热轧。当热轧高合金奥氏体不锈钢扁坯时,在1000℃左右容易产生裂纹。降低表面温度至低于950℃能恢复奥氏体相的再加
Japanese Patent Publication No. Sho 61-055571B. The austenitic stainless steel slabs containing Cr16-26% and Ni12-22% were subjected to diffusion annealing at 1100-1300 ° C. Hot rolling starts after the surface temperature drops to 950 ° C. When hot-rolled high-alloy austenitic stainless steel slab, easy to produce cracks at about 1000 ℃. Lowering the surface temperature below 950 ° C will restore the austenite phase
