一、前 言 18Cr2Ni4W钢是一种常用的高强度结构钢,一般常用作为渗碳钢使用,近年来为适应某些高强度结构零件的需要,对这种钢低碳马氏体状态的使用也渐趋普遍。随着工业生产的发展对零件的力学性能要求越来越严格,大部分零件在服役过程中承受一定的疲劳载荷,为了考核18Cr2Ni4W钢在疲劳载荷下的承载能力,本文将探讨该钢在疲劳过程中的某些性态。
I. Introduction 18Cr2Ni4W steel is a commonly used high-strength structural steel, commonly used as carburizing steel, in recent years to meet the needs of some high-strength structural components, the use of low-carbon martensitic state of this steel gradually Common trend. With the development of industrial production on the mechanical properties of parts more stringent requirements, most of the parts in the service process to withstand some fatigue load, in order to assess the bearing capacity of 18Cr2Ni4W steel under fatigue load, this article will explore the steel in the fatigue process In some of the character.
