An element that closely resembles sulfur in its properties. A metalloid melting point of 220°C (428°F) added to stainless steel to improve machinability. The main use in steel is as a free-cutting additive, but due to high-cost, it is limited to stainless steel. One of the benefits being the ability to obtain a very good surface finish on machined components. An element that closely resembles sulphur in its properities.
