AISI 12L14 JIS SUM24L Free Cutting Steel Cold Drawn Round Bar/Rod
1.Introduction of 12L14 free steel steel:
12L14 - COLD DRAWN ROUND ROD
Cold Drawn Round 12L14 Carbon Steel Bar/Rods are best known for their excellent machinability due to its added Lead content.
12L14 Cold Drawn Steel Rods are frequently used to fabricate high speed machinery. It has very high machinability
AISI 12L14 is a Standard Resulfurized and Rephosphorized grade Carbon Steel. It is a free machining steel and is commonly called AISI 12L14 Lead Steel.. Lead has been added to the chemical composition to provide an improved level of machinability. Although machinability is excellent, the added lead content reduces the overall strength of that steel.
2.Alternative steel grades to 12L14
Free machining bar 12L14FM is supplied as per one of the following alternative standards.
1) AS1443 grade 12L14, ASTM A108 grade 12L14.
2) ASTM A108 grade 1213 or grade 1215,
3) Euro norm EN 10087 grade 11SMnPb37 (1.0737).

5.Common application
It is mainly used in the production of instruments, watch parts, automobiles, machine tools and various other machines that require less force and have strict requirements on size and finish. It has strict requirements on dimensional accuracy and finish, but relatively low requirements on mechanical properties. Standard parts such as gears, shafts, bolts, valves, bushings, pins, pipe joints, spring cushions and machine tool screws, plastic molding molds, surgical and dental surgical appliances, etc.
