Otomat Çelikleri

Yüksek hızlı işleme için çelikler

Yaygın olarak otomat çelikleri olarak adlandırılan yüksek hızlı işleme için çelikler, talaş kaldırma ile yüksek verimlilikle işlenecek şekilde özel olarak tasarlanmıştır.

Otomobil endüstrisi ve ev aletleri gibi birçok seri üretim alanında yaygın olarak kullanılan otomat çelikleri kükürt, tellür, bizmut ve kurşun gibi elementler içerir.

İçeriğindeki kükürt talaşın parçalanmasını sağlarken; kurşun, takım ve parça arasındaki sürtünmeyi azaltarak takımların ömrünü uzatır. Tellür ve bizmut bu özellikleri daha da belirgin hale getirir. Otomat çelikleri, genellikle ısıl işlemsiz çubuk halinde tedarik edilir. Bazı otomat çelikleri ise son işlem olarak temperlenebilir, normalize edilebilir veya tavlanabilir.

11SMn30 1.0715 Steel with the addition of sulfur only, with good machinability.
11SMn37 1.0736 Steel with the addition of sulfur only, in higher quantities than in 11SMn30; increased machinability at the expense of a slightly more accentuated fragility
11SMnPb30 1.0718 Free-cutting steel with the addition of lead to increase chip removal productivity. It is the most common type in Germany. Good machinability.
11SMnPb37 1.0737 Free-cutting steel with the addition of lead similar to the previous one, but with a higher sulfur content. It is the most common type in Italy and France. Excellent machinability. The Telyx version has a further improved machinability with respect to 11SMnPb37.
11SMnPb30+Te+Bi 1.0718 Steel with the addition of sulfur, lead, tellurium, and bismuth; allows a very high cutting speed of the tool with excellent finishes. Also has a particular cold deformability.
11SMnPb37+Te+Bi 1.0737 Steel similar to the previous one, but with a higher sulfur content; reaches the maximum levels of machinability, combining all of the advantages tied to productivity in a single product.
28SMnPb28 This steel is not unified in the standards. It is used when you want to obtain a mechanical resistance of approximately 600 MPa, not achievable with other low-carbon free-cutting steels, while maintaining good machinability. Not suitable for heat treatments.

10SPb20 1.0722 The most widespread carburized free-cutting steel; the addition of silicon guarantees the uniformity of the austenitic grain, while the limited percentage of sulfur allows a successful hardening treatment after carburizing.

35S20 1.0726 Steel with low carbon content and with the addition of sulfur for improved machinability.
46S20 1.0727 Steel with the addition of sulfur only; the higher carbon content gives this quenched and tempered steel greater mechanical characteristics.
38SMn28 +Se 1.0760 Free-cutting steel with an average carbon content; the addition of tellurium allows an even better machinability.
44SMn28 1.0762 Free-cutting steel with sulfur only, with a high carbon content to obtain optimal hardness after tempering.
44SMnPb28 1.0763 Steel with the addition of sulfur and lead; the special carbon content allows excellent hardness to be obtained after tempering.
36SMnPb14 1.0765 Classic quenched and tempered free-cutting steel with the addition of sulfur and lead. The SAE1137Pb version, with the same composition, has a slightly higher temperability and is used for products delivered at the quenched and tempered state.
