Introduction of 16MnD5 nuclear power steel

Posted:2022-01-24 11:14:13

16MnD5 nuclear power steel is a medium carbon quenched and tempered steel with good strength, toughness and hardenability. After quenching and tempering, it can obtain better comprehensive mechanical properties such as high fatigue strength and multiple impact resistance. It has no apparent temper brittleness.

16MnD5 steel plate delivery status: quenching + tempering.

Chemical composition and melting analysis of 16MnD5 steel plate:
