Spark-Testing-Standard Pieces
A spark test standard piece is a sample that allows you to easily and quickly identify the steel type of a steel material using a grinder spark. The spark test allows the machine material to be selected accurately. The spark test standard piece is a sample to identify 45 JIS standard steel types and is generally used at construction sites. Therefore, the easy-to-distinguish grinder spark helps you, when you want to compare, collate, and appraise the types of JIS steel materials. It is necessary to distinguish steel types at the time of heat treatment, material management, and various mechanical design processes. The spark test standard piece requires only some equipment such as a spark test booth, not large-scale equipment, to identify steel types, featuring the reduction of the equipment cost and less time and effort to be required.
