AISI 12L14

Typical analysis

C	Mn	P	S
max. 0.15	0.85 - 1.15	0.04 - 0.09	0.26 - 0.35

C 12L14 is essentially resulfurized and rephosphorized screw machine stock to which lead has been added.

Typical applications

Used to maximum advantage for parts where considerable machining is required such as bushings, inserts, couplings and hydraulic hose fittings. With good ductility, these grades are suitable for parts involving bending, crimping or riveting.

Mechanical properties

Tensile strength	PSI	87,500
Yield point	PSI	75,000
Elongation	% in 2"	15
Reduction in area	%	50
Brinell hardness		163/179

Machinability

12L14 has a machinability rating of 198% of AISI B-1112. Average surface cutting is 325 feet per minute.

Weldability

Due to high sulfur content, these grades are not considered as weldable.

Hardening

Although these grades will respond to conventional treatments, they are not considered case-hardening steels. Better results can be obtained from 1117 or 1018.
