On the flip side, 1215 carbon steel is not as cheap as 1018 in raw material form but has a 25-40% overall cost reduction. This is due to the higher machining speeds and efficiencies gained by the addition of Sulphur and Phosphorous into the material.
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. A Leadless Machining World:Interview with Miles Free 2 thoughts on A Leadless Machining World:Interview with Miles Free Tom Johnson June 1, 2010 at 2:04 pm. Do you have any thoughts on the California AB-1953 lead restriction? The regulation allows lead up to .25%, while 12L14 has an allowable range of up to .35% therefore not allowing use of the 12L14 unless there is selective use of heats containing under the .25%
A lead -free alternative to 12L14, 1215 carbon steel contains the same amount of sulfur and phosphorus for excellent machinability. It is often used for shaft couplings, studs, and pins. Easy-to-Machine 1215 Carbon Steel Hex Bars Cutting Speeds - LittleMachineShopMaterial:AISI/SAE/ASTM Designation:HSS Feet/Minute:Carbide Feet/Minute:Free machining plain carbon steels (resulfurized) 1212, 1213, 1215:270 - 290:820 - 1045

Work for a leader in precision transfer machine technology. See job openings here. Contact Information. Free Cutting Steel Supply from Taiwan - JFS Steel steel Free machining steel is steel that forms small chips when machined. This increases the machinability of the material by breaking the chips into small pieces, thus avoiding entanglement in the machinery. This enables automatic equipment to run without human interaction. Free machining steel with lead also allow for higher machining rates.
A free machining, resulphurized, lead-bearing steel for high volume production parts. 1215 The A.I.S.I. grade 1215 has essentially eliminated a number of similar free machining Niagara Lasalle Steel Products - Grade 1215General The A.I.S.I. grade 1215 has essentially eliminated a number of similar free machining grades, such as 1212. Both 1215 and 1213 machine considerably faster than 1212 and provide good surface finish and brazing properties. These steels are difficult to weld and are not recommended for case hardening.

Both 1215 and 1213 machine considerably faster than 1212 and provide good surface finish and brazing properties. These steels are difficult to weld and are not recommended for case hardening. S1214 Bright Carbon Steel Bar Interlloy Engineering S1214 is a free machining low tensile, low hardenability carbon steel generally supplied in the cold drawn or turned and polished condition, with a typical tensile strength range 370 - 760 Mpa, and Brinell hardness range 105 - 225.Characterised by excellent machinability, moderate weldability, with reasonable strength and ductility.
1215 is a resulphurized and rephosphorized free machining steel, commonly referred to as screw machine stock. 1215 is an improved free machining steel that has replaced the Bessemer B1113 grade years ago. 1215 is especially suited for automatic screw machine operations where the major requirement is exceptional free-machining quality with a Weldability of Free Machining Grades of SteelAmerican Iron and Steel Institute (AISI) and Society of Automotive Engineers (SAE) alloy series 1141 (i.e. AISI-SAE 1141) is considered a heat treatable, "free machining" (or free cutting) grade of carbon steel. Free machining types of steel contain higher levels of sulfur (0.05% or more), phosphorus (0.04% or more) or lead for improved
Oct 16, 2013 · It will take 5 minutes to learn how to machine 1018 and the rest of your life to live down a fubar from welding free machining steel. A no brainier if there eaver was one. oldbikerdude37 , tdmidget liked this post What is free machining steel? - RyersonFor instance, one of the most commonly used free machining steel grades is 12L14 bar. This is a standard resulfurized and rephosphorized grade carbon steel that can often be found in automatic screw machines that manufacture such parts as
Excessive phosphorus, however, impairs machining characteristics, while decreasing as-rolled steel ductility and notch impact toughness. Lead additions to free-machining steel are generally in the range of 0.15 to 0.35 percent. Lead is present in steel as soft particles that enhance the formation of microvoids during machining.1215 Free Cutting Steel Supply from Taiwan - JFS Steel Equivalent Grades:GB 4Cr5MoSiV1, JIS SKD61, ASTM H13, DIN X40CrMoV5-1. 1215 free cutting steels are utilized primarily to manufacture the parts which have the requirements of high precision in size, high finish in surface, but low mechanical property, such as gears, shafts, bolts, valves, bushings, pins, fittings, spring seat and machine screw, plastic mold, surgical and
