This austenitic stainless steel, known for its free-machining characteristics, possesses a unique combination of sulfur and selenium additions. This composition results in improved machinability while maintaining adequate corrosion resistance and mechanical properties suitable for various applications. Typical uses include fasteners, shafts, and gears.
The enhanced machinability offered by this specific grade reduces production time and tooling costs, making it a cost-effective choice for high-volume manufacturing. Its resistance to atmospheric corrosion and certain mild chemical environments ensures component longevity. Historically, the development of this material addressed the need for easily machined stainless steel suitable for complex parts. Its ongoing popularity reflects its continued relevance in industries demanding efficient, durable, and corrosion-resistant components.
