What is 11L17 steel?
11L17 is a low-carbon, high-manganese steel. The addition of lead and manganese to this steel increases hardenability and machinability without compromising carburizing properties. 11L17 can handle moderate cold working.
What is 12L14 steel?
12L14 is a standard resulfurized and rephosphorized carbon steel. Lead is also added in order to increase machinability, and it also means it can be bent, riveted, or crimped. However, this extra ductility and machinability do mean that 12L14 is slightly weaker than comparable carbon steel alloys.
Can you weld 12L14?
12L14 should never be welded for critical weldments like lifting lugs, or fittings where high pressure and cyclic loads are encountered. Because of the lead content, the melting point at grain boundaries is lowered and areas that reach that temperature sort of melt even though they are obviously not part of the weld.
Can you weld 1117 steel?
The 1117 steel is a resulphurized, free machining steel with 0.08 – 0.13% sulphur added to make it easy to machine. It is generally recommended that these steels not be welded. The high sulfur makes the welds prone to “hot cracking”, in which cracking occurs during welding.
What is C1117 steel?
Alro stocks C1117 – a low carbon, high manganese steel. Machinability is improved over 1018, and case hardening is deep and uniform, supported by a tough ductile core. 1117 is a resulphurized steel with superior case hardening characteristics.
Is 12L14 OK to harden?
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.
Can 12L14 be heat treated?
Typically, you need a bit of carbon to get hardness with heat treat. 12L14 is leaded, rephosphorylized and resulfurized steel which makes it free machining, but it only has 0.14% carbon. You can case harden blunt objects of it using heat-treatment with a long soak in a bed of carbon, or with Kasenit or Cherry red .
Can 12L14 ledloy be welded?
The problem is while the lead is good for machining…its bad for welding. 12L14 should never be welded for critical weldments like lifting lugs, or fittings where high pressure and cyclic loads are encountered. that said…12L14 CAN be welded…. and there are a few things that help make it go better.
