一、概述不锈钢的研究工作,早在十九世纪就开始了。在本世纪二十年代开始进行工业性生产。不锈钢随着工业的发展和科学研究的进展也不断得到发展。在自动控制系统的精密仪器中,常有一些部件在磁场中工作。这除了对钢的耐蚀性和强度有一定要求外,还特别提出钢的低磁性能。要求钢有极低的导磁率,即不因零件本身的磁化而影响电磁场的正常工作。因此低磁不锈钢(或称“抗磁不锈钢”)是自控系统和精密仪器技术发展过程中,对不锈钢提出的一项新要求。
First, an overview of stainless steel research, as early as the 19th century began. In the twenties of this century began industrial production. Stainless steel with the development of industry and scientific progress has also been continuously developed. In the automatic control system of precision instruments, there are often some components in the magnetic field work. In addition to the corrosion resistance and strength of steel have certain requirements, but also made special mention of low magnetic properties of steel. Requires steel has a very low permeability, that is not due to the magnetization of the parts themselves affect the normal work of the electromagnetic field. Therefore, low-magnetic stainless steel (or “anti-magnetic stainless steel”) is a new requirement for stainless steel in the development of automatic control systems and precision instrumentation.
