Mechanical properties of normalized Q460E could reach the requirement of some medium carbon quenched and tempered steel. Q460E鋼正火可以達到某些中碳調質鋼的力學性能要求。 www.jxcad.com.cn
Being compared with the normalized steel, the quenched and tempered steel can led to a joint with higher strength and toughness. 正火態與調質態母材相比，後者可得到強靭性較高的接頭。 www.jxcad.com.cn
To produce non-quenched and tempered N80 steel with low cost, the difficulty is how to add the nitrogen and how to control the content of then. 如何增氮以及怎樣控制鋼液中氮含量是低成本生産非調質N80鋼的難點。
