Product Description

AISI 1215 Bright Free Cutting Steel Round Bar / Square Bar / Hexagon 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.
