Ürün Açıklaması

AISI 12L14 Low Carbon Leaded Free Cutting Steel, bright drawn or smooth turned with a consistently excellent level of machinability. The lead improves machinability greatly with little effect on the mechanical properties.

TYPICAL APPLICATIONS:

Very heavily machined components or parts subject to low stress levels, low shock loading, limited forming and very limited welding.

DIMENSIONAL TOLERANCES:

Bright drawn / Smooth turned:  h10

TYPICAL CHEMICAL ANALYSIS:

Carbon	0.07%
Silicon	0.01%
Manganese	1.00%
Phosphorus	0.05%
Sulphur	0.30%
Lead	0.25%

Manganese/Sulphides plus the lead addition assist chip formation, friction and wear on cutting tool is reduced, allowing higher feeds and/or speeds.
Hot or cold forming is limited due to the high sulphur content.
Not suitable for through hardening flame or induction hardening due to the low carbon content.

Will Carburise or Carbonitride - Typical surface hardness to HRC 58.
Ref AISI 1215 for details

PLATING:

Will electroplate but not suitable for hot dip galvanizing

WELDING: Must be carried out in a well-ventilated environment or avoided as the lead will give off toxic fumes. Ref AISI 1215 for details
