摘要: A hot-stamp formed body has a predetermined chemical composition and has a microstructure including, by area ratio, martensite: 90% to 100% and a remainder in the microstructure: 0% to 10%. The percentage of martensite having a GAIQ value of 40000 or less in all of the martensite is less than 5.0%, an average grain size of prior austenite grains is 6.0 µm or less, and a standard deviation of grain sizes of the prior austenite grains is 2.6 µm or less.
