摘要：
A steel sheet for an explosion-proof band contains 0.001 to 0.05% by mass of C, 0.2 to 1% by mass of Si, 0.5 to 2.3% by mass of Mn, 0.02 to 0.12% by mass of P, not higher than 0.005% by mass of 0, not higher than 0.020% by mass of S, and not higher than 0.005% by mass of N, and has not higher than 100% of a P segregation rate within the steel sheet, which is represented by (Pmax−Pave)×100/Pave, where Pmax denotes the maximum P concentration within the steel sheet, and Pave denotes the average P concentration within the steel sheet, 10 to 25 μm of an average ferrite grain size, and not lower than 10,000 of an anhysteretic magnetic permeability.
