12L14 Round Bar: Material Profile

12L14 is widely used for precision turned parts where cycle time, surface finish, and dimensional consistency matter.

It is intended for machining rather than welding, high-strength parts, or elevated-temperature service.

Purchase to the controlling ASTM, SAE, AMS, or customer specification. Section size, supply condition, mechanical properties, surface limits, testing, and heat/lot traceability can change the acceptable material and processing route.

Key Characteristics

Exceptional machinability
Good surface finish
Extended cutting-tool life
Close dimensional tolerances

Common Applications

Valves and fittings
Bushings and inserts
Fasteners
Hydraulic hose components

Typical Chemical Range

Element	Weight %
Carbon (max)	0.15
Manganese	0.85–1.15
Phosphorus	0.04–0.09
Sulfur	0.26–0.35
Lead	0.15–0.35

Chemistry ranges are general reference values. The purchase specification and material certification govern the order.
