摘要： PROBLEM TO BE SOLVED: To provide a method for producing a non-heat treated high strength bolt with which the relaxation of this bolt is improved and the suitable low temperature toughness as this bolt is obtained.
SOLUTION: At first, a steel material having the prescribed components for producing the non-heat treated high strength bolt, is melted (S10), and successively, this steel material is rolled into a wire rod, and a patenting treatment is applied. Further, the cross section is drawn to make the prescribed steel wire (S12). Thereafter, a press-forming is applied into the bolt-shape by deciding a reduction of area from the diameter of the steel wire to the cross section having effective diameter (S14). Then, the tensile stress is loaded in the axial direction of the formed bolt. This loading is applied with the tensile stress having not more than the elastic limit of the bolt material (S16). Then, under this loading or after separating from this loading, the prescribed heat treatment is applied (S18-S24).
