摘要: Disclosed is a zirconium alloy material having high corrosion resistance regardless of thermal history during its manufacturing process. The obtained by providing containing on the mass basis: 0.001% to 1.9% Sn, 0.01% 0.3% Fe, Cr, Ni, 3.0% Nb, 0.027% or less C, 0.025% N, 4.5% Hf and 0.16% O with remainder being inevitable impurities zirconium, formed bulk surface layer, in which layer has plastic strain 3 more Vickers hardness 260 HV an arithmetic mean roughness Ra 0.2 μm less.
