FIELD: metallurgy.
SUBSTANCE: sheet is made of steel containing in wt %: 0.85-1.20 C, 0.05-2.00 Si, 0.05-0.50 Mn, 0.05-0.60 Cr, P ≤ 0.0150, Fe and unavoidable impurities making the rest. At least 97% of the head surface part located in area from head angular and top parts as initial point to depth of 10 mm features perlite structure. Perlite structure Vickers hardness makes HV 320-500. CMn/FMn ratio makes 1.0-5.0, where CMn [at %] is Mn concentration in cementite phase in perlite structure, FMn [at %] is Mn concentration in ferrite phase.
EFFECT: high wear resistance and impact strength.
