PROBLEM TO BE SOLVED: To provide steel as a material for a metal band saw blade body which shows a high producibility and excellent plate-bending fatigue characteristics. SOLUTION: The steel as the material for the band saw blade body comprises, by mass, 0.25-0.45% C, 0.05-2.0% Si, 0.10-1.0% Mn,≤0.020% P,≤0.010% S, 1.0-2.5% Cr, 1.0-2.5% Mo, 0.05-1.0% V, 0.01-0.1% Ti, 0.01-0.1% Nb and the balance being Fe and unavoidable impurities, optionally further comprises 0.1-2.0% Ni and 0.0005-0.01% B and preferably comprises≤30 ppm O. Here, a Ti equivalent defined by the equation: Ti equivalent=2×Ti+Nb is 0.05-0.23, and a value A defined by the equation: value A=8×C+4×Si+3×Mo+2×V+Cr is preferably 10-14. COPYRIGHT: (C)2004,JPO
