Feature: The influence of merchantmen on property of 15NiCuMoNb5-6-4 pipe is researched. It is found that hardness descend and then raise, and strength gradually descend when tempering temperature ascend. Hardness descend and toughness raise when tempering time add. The best tempering technical of this steel is that tempering temperature is 630-660℃.
