近年来,随着与石油、天然气、炼铁相关设备的发展,用于压力输送气体离心压缩机的叶轮也要求使用高性能的高强度不锈钢。最近,为了开发加工性(锻造、压延、机械加工)、焊接性、韧性、低热膨胀率、耐蚀性和再循环性等各种性能都良好的材料,并以改善这些性能为目标,日本石川岛播磨重工业公司开发了低C—16Cr-5Ni系马氏体不锈钢(简称IS钢)。已在第1、2、3篇报告中作了
In recent years, with the development of equipment related to oil, gas and ironmaking, impellers for pressure-fed gas centrifugal compressors also require the use of high-performance, high-strength stainless steel. Recently, in order to develop materials having various properties such as workability (forging, rolling, machining), weldability, toughness, low coefficient of thermal expansion, corrosion resistance and recyclability and to improve these properties, Island Broadcasting mill heavy industry developed a low C-16Cr-5Ni martensitic stainless steel (referred to as IS steel). It was made in the first, second and third articles
