1215 Cold Drawn Square Steel Bar
1215 steel is one kind of free cutting steel, sometimes with higher Sulphur content as 1215S material which offers cleaner finishes and higher tolerances. It is often takes as a higher quality alternative steel grade than 1018 steel with better machining and cutting properties. 1215 material can minimize tooling maintenance and improve the cutting ability and machine life of equipment. The most popular 1215 steel bar includes: steel round bar, Bright Steel Bar, Hexagon Steel Bar and Cold Drawn Steel Bar and cold drawn square bar.
