EFFECT OF HEAT TREATMENT AND AGING ON THE COLD RESISTANCE OF PIPE STEEL, STRENGTH CATEGORY K60
The paper investigates the effect of heat treatment and aging on the low-temperature viscosity of pipe steel, strength category K60, which has not undergone antifloken treatment (AFT). The dependence between the duration of aging of hot-rolled thick-rolled products that have not passed the AFT and cold resistance has been determined. The scientific substantiation of influence of the atomic hydrogen molization is proposed, during the eutectoid reaction, on the cold resistance of K60 steel.
