Free cutting stainless steel refers to the stainless steel added a certain amount of one or more than one kind of sulfur, phosphorus, lead, calcium, selenium, pounds of free cutting elements, in order to improve its cutting performance, this kind of steel is mainly used in automatic cutting machine tools processing. With the development of automation, high speed and precision of mechanical processing, the steel is required to have good cutting performance to adapt to mass production. In order to ensure the processing yield and service life of the material, the material is also required to have good plasticity and corrosion resistance.
