What material is free-cutting steel?

Product description: Free-cutting steel is an alloy steel that improves machinability by adding certain amounts of sulfur, phosphorus, lead, calcium, selenium, tellurium, and other free-cutting elements to ordinary steel. The English name is free cutting steel (also known as automatic machine tool processing steel, abbreviated as automatic steel). This steel can be machined at higher cutting speeds and greater cutting depths. The added free-cutting elements reduce cutting resistance, and the characteristics of these elements and the compounds they form lubricate the cutting tools, resulting in easy chip breaking, reduced wear, lower workpiece surface roughness, extended tool life, and increased production efficiency. It is one of the most widely used steel types daily.

 

What are the common free-cutting steel materials?

 

Answer: The most commonly used free-cutting material grades on the market: 1215, sum24l, 11smnpb30c, 9smnpb28k, 9smn28k, sae1215, 9smnPb36, 11smn37, SUM22, aisi1018, sae1018, 12L15, 11smnpb37, 44smn28, 44smn28, sae44smn28, aisi44smn28.

 

 

What are the classifications of free-cutting steel?

 

Answer: Classified by elements: sulfur free-cutting steel, lead free-cutting steel, calcium free-cutting steel, selenium, tellurium, bismuth free-cutting steel.

 

  The five major advantages of 44smn28 free-cutting steel as delivered: excellent electroplating performance, beautiful surface finish, environmentally friendly, high precision, and easy processing without damaging tools.

 

 

What are the main uses of the product?

 

Answer: Widely used in hardware tools, automotive parts, standard parts, fasteners, general shaft parts, machinery manufacturing, light industrial parts, hardware accessories, standard parts, bicycles. Free-cutting steel is mainly used to manufacture instruments and meters with small stress but strict requirements on size and finish, watch parts, automotive, machine tools, and various other machines. It is used for standard parts that require strict dimensional accuracy and finish but relatively low mechanical performance requirements, such as gears, shafts, bolts, valves, bushings, pins, pipe fittings, spring seats, machine tool lead screws, plastic molding dies, surgical and dental instruments, textile machinery, etc.
