设计了用于合团相颗粒的高温碱溶液下的双相铸造不锈钢KM／2钢的组织和化学成分。试验表明具有双相组织的KM-2铸造不锈钢在含有固相颗粒的高温碱介质条件下具有较好的耐蚀性能，同时具有良好的铸造性能。由KM-2制做的泵件寿命比316钢提高一倍。
The microstructure and chemical composition of duplex stainless steel KM / 2 steel were designed for high temperature alkaline solution of co-phase particles. Tests show that the KM-2 cast stainless steel with dual phase structure has good corrosion resistance under high temperature alkaline medium containing solid particles, and has good casting performance. Pumps made from KM-2 double the life of 316 steel.
