Have steel milled and turned

In the area of low-alloy steels, we offer you the most common structural steels, free-cutting steels, case-hardening steels and quenched and tempered steels for turning and milling. These are versatile materials with good mechanical properties and low price. At Spanflug Buy you can choose from eight different steels for CNC machining (milling and turning). Our overview will help you choose the ideal material for your turned and milled parts.

Heat and surface treatments for turned and milled steel parts

For our steels you can choose from a wide range of Heat and surface treatments such as hardening, nitriding, burnishing, galvanizing and chromium plating.

This is how easy it is to order steel parts from Spanflug:
