一、前言 在本题的(Ⅰ)中,作者介绍了取代1Cr18Ni9Ti的目的意义,以及从新钢种的成份确定、生产成本、加工工艺、力学性能、点蚀电位等角度对可行性作了基本肯定。现本文主要就欲取代1Cr18Ni9Ti的新钢种的耐蚀性能和深冲性能以及应用情况对其可行性作进一步的论述。 在本题(Ⅰ)发表的同时,新钢种的课题研究工作也在顺利地进行。稍后,于1989年,新钢种也得以通过有关方面的技术鉴定。所以本文将在论述中采用鉴定时所用的
I. Introduction In this section (I), the author introduces the purpose of replacing 1Cr18Ni9Ti, and confirms the feasibility of the new type of steel from the aspects of composition determination, production cost, processing technology, mechanical properties and pitting potential. This paper is mainly to replace the new 1Cr18Ni9Ti corrosion resistance of steel and deep drawing properties and application of its feasibility for further discussion. At the same time as this (I) was published, the research work on the new type of steel was also proceeding smoothly. Later, in 1989, the new steel grades were also passed technical appraisals. So this article will be used in the discussion of the identification used
