Description

Carbon Steel Square Bar C12L is a leaded carbon steel square bar known for its excellent machinability. The addition of lead makes this square bar ideal for high-speed machining and turning, allowing for faster production times and reduced tool wear. It is commonly used in applications that require precision machining, such as parts for automotive, machinery, and other industrial uses. While it offers superior machining capabilities, it is best suited for low-stress applications where corrosion resistance is not a primary concern.

About C12L steel

C12L is 12L14, the leaded free-machining steel: about as easy to cut as steel gets. The lead breaks the chip and lets the tool fly, so it turns, drills, and threads fast with a clean finish. Reach for it on high-volume machined parts, fittings, and fasteners where machinability is the whole game. It's low strength and not for welding, so keep it off load-bearing and welded work.

What is 12L14 steel good for?
Fast, high-volume machining: fittings, fasteners, pins, and screw-machine parts. The lead makes it one of the most machinable steels there is. The trade is low strength and poor weldability, so it's a machining steel, not a structural one.
