摘要
文章介绍了非调质钢的概念、分类及其特点,总结了我国研制的非调质抽油杆钢的应用情况,分析了钢中元素作用及强韧化机理,指出不断发展的新型非调质钢将会使抽油杆生产迈上新台阶。
The paper introduces its concept, types and characteristics about un- quenched and un- tempered steel, and summarizes the application of un - quenched and nn - tempered steel for sucker rod developed in China, then analyses the mechanism of strengthening and toughening. The article points out that new developing un - quenched and un - tempered steel will impulse the production of sucker rod.
