The invention relates to a manufacturing method for nickel-chrome steel used for a storage tank. The manufacturing method for the nickel-chrome steel used for the storage tank comprises, by weight, 0.01-0.10% of C, 0.10-0.35% of Si, 0.45-0.76% of Mn, 4.5-6.5% of Ni, 0-0.005% of S, 0-0.008% of P, 0.015-0.050% of Als, and the balance Fe and unavoidable impurities. The manufacturing method for the nickel-chrome steel used for the storage tank ensures the steel strength and plasticity of the steel and improves the anti-seismic property, corrosion resisting property and the like of the steel. 本发明涉及储罐用含镍铬钢的制造方法，其化学成分按重量百分比计为：C：0.01~0.10%，Si：0.10~0.35%，Mn：0.45~0.76%，Ni：4.5~6.5%，S：≤0.005%，P：≤0.008%，Als：0.015~0.050%，余量为Fe和不可避免的杂质；本发明提供的储罐用含镍铬钢的制造方法，在保证钢材强度和塑韧性的同时，也提高了钢材的抗震性能、耐蚀性能等功能。
