Can 12L14 steel be heat treated?
12L14 has the standard machining cost factor of 1.0 that our materials are measured against. It is not ideal for welding due to its high sulfur content. 12L14 will respond to heat treatment, but is not considered case-hardening.
What does 12L14 steel mean?
12L14 is a lead-bearing steel with average machining rates that are 30-40% faster than 1215, which is another commonly used grade in this series.
Is 12L14 mild steel?
12L14 is a Re-Sulphurised, Re-Phosphorised Free Maching Steel. This is premium grade of free cutting steel is used by repitition engineers and general machining for a wide variety of applicaitons. It has excellent machinability and is suitable for case hardening and electroplating.
What is 12L14 steel used for?
12L14 is used extensively in automatic screw machines for manufacturing numerous parts requiring considerable machining and close tolerances, along with a smooth finish. 12L14 can be used to maximum advantage where considerable machining is required. 12L14 is suitable for parts involving crimping, bending, or riveting.
Is 12L14 stainless steel?

Is 12L14 A low carbon steel?
Cold drawn 12L14 steel bar is a resulfurized and rephosphorized carbon steel. This grade is considered free machining, having excellent machinability due to its added sulfur, phosphorus, and lead. Due to its low carbon, this material has lower strength than other cold drawn grades.
What is 12L14 carbon steel?
Small quantities of molybdenum, chromium, nickel, aluminium, and copper are also present in these steels. AISI 12L14 carbon steel is known as the fastest machining bar product. The following datasheet will discuss in detail about AISI 12L14 carbon steel.
What is the machinability rating of AISI 12L14 carbon steel?
Other designations that are equivalent to AISI 12L14 carbon steel include: The machinability rating of AISI 12L14 carbon steel is 190. It can be machined by dispersing lead particles all over the steel. Do you have a review, update or anything you would like to add to this article?
What sizes do 12L14 cold drawn steel bars come in?
Eaton Steel Bar Company supplies 12L14 cold drawn steel bar in a variety of sizes ranging from – 5/16”-11”. The shapes available for this grade include: Interested in Eaton Steel’s Cold Rolled Catalog?
How do you re-heat 12L14 steel?
Re-heat 12L14 steel to 120℃ – 230℃, hold until temperature is uniform throughout the section, soak for 1 hour per 25 mm of section and cool in still air.NB. Tempering will improve the toughness of the case with only slight reduction in case hardness. It will also reduce it’s susceptibility to grinding cracks.
