日前,抚顺特钢集团公司的特殊钢品种T91质量技术攻关项目取得突破性进展。该公司在生产出高质量流钢砖之后,按照相同探伤标准探伤了14炉43支锭,全部消除了夹杂物。T91在国外被称为铁素体耐热钢,退火前的组织为马氏体不锈钢,退火后为铁素体。该钢主要用于核电和火电30万千瓦或超 Recently, Fushun Special Steel Group’s special steel products T91 quality technology breakthrough project made breakthroughs. After producing high-quality steel-flow bricks, the company flawed 14 furnaces in 14 furnaces under the same flaw detection standard, completely eliminating inclusions. T91 abroad is called ferritic heat-resistant steel, the organization before annealing is martensitic stainless steel, ferrite after annealing. The steel is mainly used for nuclear power and thermal power 300,000 kilowatts or super
