| Abstract: | In this paper, by chemical composition and microstructure design, a new cryogenic cast steel ZG 1Mn19Ni3Al was developed. The mechanical properties of weld plate were tested and their fracture behaviors were studied. Experimental results showed that the inclusions and welding heat input have remarkable effect on low temperature impact toughness. ZG 1Mn19Ni3Al casting steel with micro duplex structure of γ+ε phrases can be used for cast welding structure at low temperature(down to -196℃), when the finishing process and suitable welding heat input are adopted. |
