这一部分介绍中温用钢(包括抗氢钢)、不锈钢和耐热钢、不锈钢复合钢板等方面的有关情况。一、中温用钢(包括抗氢钢) 国内至今尚未制订出中温用钢厚钢板的技术条件(国家标准或冶金部标准),因此在压力容器用钢板中,中温用钢方面的问题就更多一些。迄今国内中温压力容器用钼钢和铬钼钢钢板大部分靠国外进口,少部分由国内有关钢厂进行试制。 1985年版的《设计规定》中,钢板部分列
This section describes the temperature of steel (including hydrogen steel), stainless steel and heat-resistant steel, stainless steel clad steel and so on. First, the temperature of steel (including hydrogen resistant steel) has not yet developed a medium temperature steel plate technical conditions (national standards or the Ministry of Metallurgical standards), so the pressure vessel steel, medium temperature steel more problems some. To date, most domestic Molybdenum and Chromium-Molybdenum steel plates for medium-temperature pressure vessels are imported from abroad, and a small part is trial-produced by some domestic mills. 1985 edition of the “Design Rules”, the steel part of the column
