The present invention provides an alloy composition having a two-phase structure with excellent cryogenic toughness, which can store various liquefied gases such as hydrogen, LNG and nitrogen more safely because it exhibits excellent cryogenic impact toughness compared to conventional cryogenic high-manganese steel, and significantly increase resistance to container damage even in accidents where external impact is applied, chromium-manganese steel and a manufacturing method thereof.
