Steel & Steel Products

Our product range contains a wide range of FREE-CUTTING STEEL

FREE-CUTTING STEEL

Free-cutting steels for CNC machines and automatic lathes. The Sandvik program of free-machining steels includes carbon steel in size range 0.49-12 mm (0.0192-0.472 in.) and stainless steel in size range 0.50-80 mm (0.0196-3.15 in.).

Sandvik free-cutting steels are characterized by excellent machinability and surface finish and have tight and consistent tolerances. This contributes to increased cutting speeds, reduced tool wear and shorter set-up times.

New lead-free free-cutting steel

Sandvik Finemac, our latest development within free-cutting steel, is an environmentally friendly, lead-free material offering a wider hardening window than other free-cutting steel grades.Read more about Sandvik Finemac free-cutting steel

Material

Free-cutting steel grades

The Sandvik program of free-cutting steels includes both carbon steel and stainless steel. Technical data, such as nominal chemical composition and mechanical properties, is found in the datasheet for the respective grade.

Other grades can be offered on request.

Sizes and tolerances

Sandvik free-cutting steels have tight and consistent tolerances, reducing machine set-up times and facilitating trouble-free production.
