Product brief introduction

This steel has a low hardness during normalizing and a high processing roughness; however, it is heated at a relatively high temperature, and is normalized by means of a diffused air-cooling method after the furnace is baked to obtain a uniform fine-grained pearlite-ferrite structure. To achieve satisfactory machinability.
