Product Description

1215 1215ms Carbon Cold Drawn Free Cutting Hex 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.

Cold finished bars are produced from special bar quality hot rolled bars by cold drawing, turning, grinding, polishing, or by a combination of these methods.

Cold drawing increases a bar's yield strength and tensile strength, turning improves surface quality, grinding produces more precise tolerance ranges, and polishing further creates a smooth and attractive surface. Overall, cold finishing reduces the cross sectional area of the hot rolled bar. CF steel bars may be harder to work with than their hot rolled equivalents, but they make up for it with more accurate sizes, smooth surfaces, increased mechanical properties and machinability.

AISI 1215 Low Carbon Free Cutting Steel, bright drawn or smooth turned with a high and consistent level of machinability but limited strength and ductility.

Cold drawn steel advantages:
1.It can remove the Size and Section which provides Tighter tolerances which Reduces machining losses.
2.It can remove the  Steel Surface Finish which Reduces surface machining & improves quality.
3.It can remove the  Straightness which Facilitates automatic bar feeding in CNC.
4.It can increase the Mechanical Properties which Can reduce the need for hardening.
5.It can improve the Machinability and Productivity which Enables higher machining feeds, high tool life, yield & speeds and improved machined finish.
