Abstract
PURPOSE: To captioned blank of less heat treatment strains comprising hot working the alloy of the specific component composition composed of C, Si, Mn, Cr, etc. at the specific temperature and treating the same to the specific structure through isothermal cooling or annealing then surface hardening at the A1 transformation point or under.
CONSTITUTION: The member for surface hardened parts of less heat treatment strains comprising hot working the alloy containing C; 0.1 to 0.3%, Si; 1% or under, Mn; 1.5% or under, Cr; 0.7 to 2.5%, Al; 0.05 to 0.4%, N; 0.005 to 0.025% and one or more kinds of respectively 0.02 to 0.2% of V, Nb, Ti, Zr and the rest composed of Fe or the alloy containing one or two or more kinds of respectively 1% or under of Cu, Ni, Mo, W, Co in the abovementioned alloy or the alloy or the like further containing one or two or more kinds of elements selected from respectively 0.02 to 0.3% of S, Pb, Se, Te, B and 0.0005 to 0.01% of Ca in the abovementioned alloy at above 1000°C and treating the same to ferrite+ pearlite structure through continuous heating or isothermal annealing then applying surface hardening treatment at the A1 transformation point or under.
