摘要： The present invention provides a steel wire rod or bar which exhibits good cold deformability even though it does not undergo spheroidizing annealing after hot rolling. The steel wire rod or bar with good cold deformability is characterized in that its ferrite structure contains no less than 25 nitride and carbide particles in a mixed state or composite state per 25 &mgr;m on average in a sectional area three-fourths of the diameter within the circumference of the rod or bar. Such nitride and carbide precipitates contribute to the reduction of flow stress at temperatures raised by heat generation at the time of cold deforming.

摘要： Disclosed is a spring steel for a high corrosion resistant and high strength, which exhibits an excellent drawability without softening heat treatment after hot rolling, and which has a strength of 1900 MPa or more by quenching and tempering and an excellent corrosion resistance. The spring steel contains elements of C, Si, Mn and Cr, and elements of Ni and/or Mo in suitable amounts, the balance being essentially Fe and inevitable impurities, wherein the elements satisfy the following requirement: 2.5.ltoreq.(FP).ltoreq.4.5 2.0.ltoreq.(FP/log D).ltoreq.4.0 where D is a diameter (mm) of the rolled material, and FP=(0.23�C!+0.1).times.(0.7�Si!+1).times.(3.5�Mn!+1) .times.(2.2�Cr!+1).times.(0.4�Ni!+1).times.(3�Mo!+1) in which �element! represents mass % of the element.

摘要： A rake angle α of a cutting blade 2a of a shaving tool 2 is set to a negative value and a flat surface 4 of an appropriate length is formed on a clearance surface 3. Even when center of the shaving tool 2 and center of a wire material 1 are displaced due to the negative rake angle, a cutting component force is applied in the direction in which the wire material 1 is returned to the center of the shaving tool 2. Since unevenness of a processing surface of a wire material surface generated by a blade edge is reduced by the flat surface 4, smoothness is enhanced and surface quality is improved, so that crack generation on the blade edge and tool abrasion are suppressed.
