Wires Introduction This Japanese Industrial Standard has been prepared based on the second edition of ISO Steels for cold heading a11d cold extruding published in with some modifications of jix technical contents. Por60ns given sidelines are the matters in which the contents of the original International Standard have been modified. A list of modifications with the explanations is given in annex 1 informative.
The most recent editions of the standards including the amendments shall be applied. The process DA means a process wherein wire rods having been cold worked are annealed and further finished by cold working or a process wherein g350-71 rods are finished by cold jid after annealing.
However, manufacturing processes other than given above may be selected by agreement between the purchaser and the supplier. However, in the case by processes other than process D and process DA, they shall be subjected to the agreement between the purchaser and the supplier. Over 3 to and incl.

However, in the case where a flaw depth in necessitated to be especially controlled, they shall conform to table 7 subject to the agreement between the purchaser and the supplier. When the flaw depth is especially requested to be eontrolled for 15 mm max. Table 6 Surface flaw depth of killed steel Unit: For the tensile test, t No.
Further, whether test piece of No. In that case, the carburized layer depth measured at four positions by equally dividing the circumference adopting the position of jos maximum decarburized layer depth as an origin, and the mean value thereof shall be obtained. The sample product shall be measured for surface flaw depth with a measuring device having an appropriate precision.
