七十年代以来,国外陆续在压力容器,特别是核容器,内衬不锈钢堆焊层下发现了再热裂缝,这种裂缝是低合金高强钢再热裂缝的一种特殊形式。 18MnMoNiNb钢是我所与北京钢铁研究院共同研制的特种压力容器用钢。本文采用
Since the 1970s, reheat cracks have been found in pressure vessels, especially in nuclear containers and lined stainless steel surfacing layers. This kind of cracks is a special form of reheat cracking of low alloy high strength steel. 18MnMoNiNb steel is a special pressure vessel steel jointly developed by Beijing Institute of Iron and Steel.
