FITMACH Bars

Traditional 'free machining' stainless steel grades rely on sulfur (S) additions, forming evenly distributed manganese-rich sulfides or selenides. These act as chip breakers during machining, allowing for increased machining speeds and prolonged cutting tool life. Additionally, the 'non-metallic' inclusions can serve as a solid lubricant at the tool/workpiece interface, potentially enhancing surface finish.
