1.0718 (11SMnPb30) is a free-cutting low-carbon steel with added lead and sulfur, which improves machinability. It belongs to the group of free-cutting steels (EN 10087) and is characterized by good workability, surface quality, and dimensional accuracy. Due to its low carbon content, this steel has good weldability and can be easily cold-formed. The addition of lead and sulfur, which are known as free-cutting elements, enables the steel to be easily machined into complex shapes or small parts, making it an ideal material for machining operations such as drilling, turning, and milling.
This steel is often used in the production of small, intricate parts for the automotive, electronics, and machinery industries. It is also commonly used in the manufacturing of fittings, couplings, and hydraulic components.
