Abstract��Abstract: The effect of heat treatment process on mechanical performance and microstructure of 3.5Ni low��temperature steel was introduced in this paper. The result shows that the heat treatment of rolled 3��5Ni low��temperature steel can improve the mechanical performance by fining grain size and adjusting microstructure. Excellent low��temperature toughness can be gained by 850 �� normalized or 850 �� normalizing followed by 600 �� tempering.
