Free cutting steel
|Item||Free cutting steel|
|Introduction||Free-cutting steel refers to an alloy steel in which a certain amount of sulfur, phosphorus, lead, calcium, selenium, tellurium and other free-cutting elements are added to the steel to improve its machinability. With the automation, high-speed and precision of cutting processing, it is very important to require steel to have good machinability. This type of steel is mainly used for processing on automatic cutting machine tools, so it is also a special steel.|
