resulfurize
在翻译一篇外文文章时遇到这个概念，上网搜了一下，知道是与易切削钢有关。。哪个师傅可以讲一下具体工艺？
Sulfur lowers ductility and toughness in the transverse direction as the content increases. Weldability
decreases with increasing sulfur. Sulfur is very detrimental to surface quality, particularly in the lower
manganese steels. For these reasons, a maximum sulfur content is specified for most steels. However, for
some steels, sulfur is added to improve the machinability. Sulfur also has a pronounced tendency to
segregate. Sulfur occurs in steel primarily in the form of manganese sulfide inclusions. Obviously, greater
frequency of such inclusions is to be expected in the resulfurized grades.
最后一句中的resulfurize. 1再硫化是易切钢的冶炼方法之一，就是回硫的意思。
2易切钢是国人的叫法，美国佬习惯上叫回硫钢（回硫易切钢）。
