Such steel is not used for welded structures, is not sensitive to the formation of flockenes, and is prone to temper brittleness. Hardness of heat-treated rolled products (GOST 14959−79) HB 10 -1 = 241 MPa. Hardness without heat treatment (GOST 14959) HB 10 -1 = 285 MPa. Hardness after annealing, thick sheets (GOST 1577−93) HB 10 -1 = 229 MPa.
