前言住友公司的NMCU钢是Ni-Cu-Mo低合金钢,并以其高的强度和良好的焊接性为特色。该钢已作为耐热合金钢“15NiCuMoNb5”列入VdT(?)V法规中,并广泛用作400℃以下大型热电站压力管道材料。图1表示VdT(?)V法规中规定的”15NiCuMoNb5”钢与动力锅炉其它常用材料高温屈服强度性能
Preface Sumitomo Corporation’s NMCU steels are Ni-Cu-Mo low-alloy steels and feature high strength and good weldability. The steel has been included in the VdT (?) V regulations as a heat-resistant alloy steel “15NiCuMoNb5” and is widely used as a pressure piping material for large-scale thermal power plants below 400C. Figure 1 shows the high-temperature yield strength properties of “15NiCuMoNb5” steel and other commonly used materials for power boilers specified in the VdT (?) V regulation
