非调质微合金钢(简称非调质钢)是本世纪七十年代发展起来的一种新钢种,它的出现使机械制造工艺发生了重大变革。非调质钢是应用微合金化技术,在碳素结构中添加微量的V、Nb、Ti、N等元素,经锻造(或热轧)、空冷(或控制冷却)后,无需调质(淬火和回火),即可获得调质钢的某些机械性能。采用这种新钢种制造造零件,省去了调质及附带的校 Non-quenched and tempered micro-alloyed steel (referred to as non-quenched and tempered steel) is a new type of steel developed in the seventies of this century, its appearance has undergone major changes in the mechanical manufacturing process. Non-quenched and tempered steel is the application of micro-alloying technology, in the carbon structure to add trace amounts of V, Nb, Ti, N and other elements, forging (or hot-rolled), air cooling (or controlled cooling), without quenching And tempering), you can get some of the quenched and tempered steel mechanical properties. The use of this new type of steel manufacturing parts, eliminating the need for quenching and tending and school
