Abstract: The paper studies the mechanical properties of 15MnNiNbDR steel plate produced by Xianggang,de-scribes tensile test,cold bending test,series temperature impact test,strain aging,DWTT and CTOD test as well as the test for the effects of stress relief heat treatment on mechanical properties. The test results show that the comprehensive properties of 15MnNiNbDR steel plate produced by Xianggang are qualified,fully satisfying the requirements of spheri-cal tank for - 50 ℃ service.
