The author proves practicability of the phenomenological approach to estimation of resistibility of researched steels to formation of cold cracks (CC) in the conditions of partial tempering of martensite. The author considers the main stages of developing the proposed method and presents an algorithm of estimation of a particular steel resistibility to XT. Particular characteristic of the developed method was given. The possibility of application of the method was shown by estimation of changing of resistibility to XT of steel 30XH3M2ФА in the conditions of multilayer welding.
