Analysis Mechanical_Properties Applications Machineability_and_Weldability Heat_Treating Tolerances Speedy Metals items

Cold roll is a resulphurized, rephosphorized screw machine stock with the addition of lead. This addition of lead, plus the high sulphur and phosphorous levels, form lubricating effects resulting in extremely fast machining rates. 12L14 gives a smooth, machined surface and because of its low friction component allows for increased tool life. 12L14 is commonly referred to by the trade name Ledloy™.

ANALYSIS

12L14 cold roll bars conforms to ASTM A29, A108

MECHANICAL PROPERTIES

The above values are average and may be considered as representative of 12L14

APPLICATIONS

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, such as bushings, inserts, couplings, and hydraulic hose fittings. With good ductility, 12L14 is suitable for parts involving crimping, bending, or riveting

MACHINEABILITY AND WELDABILITY

12L14 has a machinability rating at 193% of B1112. Average cutting speed 325 ft/min. will 12L14 is not readily welded due to high sulphur content and is not recommended.

HEAT TREATING

Although 12L14 will respond to conventional treatments, it is not considered to be a case-hardening steel. Better results can be obtained with 1117 or 1018.
