The changes of mechanical properties for different thickness of 3.5Ni steel plant were studied under different heating temperature and cooling conditions of hot forming. As to recovering and improvinge the material properties from being damaged, the material test coupons which had been hot formed under the same heating and cooling conditions were re-carried out normalizing and tempering as per the different specifications. The test results provided reliable technology basis for low temperature steel products fabrication.
