Free cutting steel is the refers to alloy steel in which a certain amount of one or more easy cutting elements such as sulfur, phosphorus, lead, calcium, selenium, tellurium, etc.
Free cutting steel refers to alloy steel in which a certain amount of one or more easy cutting elements such as sulfur, phosphorus, lead, calcium, selenium, tellurium, etc. are added to the steel to improve its machinability. With the automation, high speed, and precision of cutting processing, it is very important for steel to have good machinability. This type of steel is mainly used for processing on automatic cutting machines and therefore also belongs to specialized steel.
Typical Classified:
Free cutting steel is a type of easy to cut steel in the American ASTM/AISIBI standard series, corresponding to the American standard UNS.
ASTM A681, DIN 17350, EN ISO 4957, JIS G 4404, GB/T 1229, SS14
AISI/ SAE Free Cutting Steel is a low-carbon cutting steel mainly used in the manufacturing of parts that are easy to cut.
ASTM -AISI/SAE 12L14 Free Cutting Steel | Y15Pb | SUM24L | 95MnPb28 | S250Pb Steel
ASTM A681, DIN 17350, EN ISO 4957, JIS G 4404, GB/T 1229, SS14
AISI 12L14 is a free cutting structural steel, which is a type of steel that is easily machined by cutting (turning, milling, pulling, planing, drilling, etc.), also known as automatic machine tool processing steel, abbreviated as automatic steel. It was developed to adapt to the automation of mechanical processing and assembly line production
Free Cutting Steel 1213|1.0501| SUM22 Steel
ASTM A681, DIN 17350, EN ISO 4957, JIS G 4404, GB/T 1229, SS14
AISI/ SAE 1213 easy cutting steel is a type of steel mainly used for the production of instruments, watch parts, automobiles, machine tools, and other various machines with strict requirements for size and smoothness under low stress. It is used for standard parts with strict requirements for size accuracy and smoothness, but relatively low requirements for mechanical performance, such as gears, shafts, bolts, valves, bushings, pins, pipe joints, spring seat cushions, machine tool screws, plastic molding molds, surgical and dental procedures, etc
