12L14 Free Cutting Steel Round Bar / 12L14 Cold Drawn Free Cutting Steel round square hexagonal Bars
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 tht 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) Euronorm EN 10087 grade 11SMnPb37 (1.0737).
