1SMn30+BX: The free-cutting steel that combines optimum performance and respect of the environment.

As the demands on steel evolve, our unwavering commitment to optimizing our processes persists, fueled by a passion that extends from the past through the present and into the future, driven not only by performance but also by environmental considerations. The Swiss Steel Group is now able to offer you free cutting steel without Pb for your future projects.

Conformity to standards and international designation: 

The material 11SMn30+BX can be assigned to material number 1.0715 and conforms to the standards DIN EN ISO 683-4:2018 and DIN EN 10277:2018. Boron is added by Steeltec AG in accordance with the agreement to improve machinability and is specified on the test certificate.

11SMn30+BX: The free-cutting steel Swiss Steel Group portfolio has been enriched with the lead free 11SMn30+BX – the most machinable free-cutting steel without Te, Se, Bi and Pb. Materials and areas of applications

According to the EN ISO 683-4 standard, free-cutting steels fall into the category of unalloyed or low-alloy quality steels with an increased sulphur content, although some variants may also contain lead. This special composition gives free-cutting steels their outstanding properties. The exceptional machinability of these steels is due to the presence of manganese sulphide and lead inclusions. These inclusions contribute to the excellent chip-breaking properties that make machining one of the main areas of application for free-cutting steels.

SwissCut® is a bright steel from the range of special free-cutting steels. A decisive feature in favor of this steel is its profitability. The high-performance free-cutting steels have been specially developed for high cutting speeds combined with long tool life.

The SwissCut® special free-cutting steels SC30, SC37, SC30Pb and SC37Pb have been specifically developed to maximize wear reduction and optimize cutting processes. This effect is particularly evident at cutting speeds above 100 m/min, while the SwissCut® special free-cutting steels SC37Pbplus and SC620Pbplus have an optimum chemical analysis to reduce the tendency to stick to the tool surfaces.

• Higher cutting speeds: The specific material modifications in SwissCut® enable higher cutting speeds, resulting in faster machining times.
• Longer tool life: An ingenious design of oxide inclusions suppresses tool wear, resulting in longer tool life.
• Very good chip formation: The precise design of the materials in SwissCut® enables optimal chip formation, resulting in smooth machining processes.
• High uniformity across batches: SwissCut® is characterized by remarkable consistency and uniformity across different batches.
• Marked increase in productivity: Thanks to the improved properties of SwissCut®, manufacturing companies can see an impressive increase in their productivity.
• High surface quality: The use of SwissCut® ensures outstanding surface quality of machined parts.
