Form of supply and availability of 1.2085
In stock
Available for immediate delivery from stock
Form of supply
Flat, forged, quenched and tempered
Sawn blank
The processing with the saw is a mechanical processing of the material, which results in a significantly lower unintended deformation and increased hardness for the existing structure, such as the thermal cutting.
Thus, the machined workpiece has a homogeneous structure even at the edge, which does not change in the continuation of the material.
This circumstance allows immediate finishing of the workpiece with milling or drilling . So it is not necessary to anneal the material or make a similar operation beforehand.
Frequently asked questions about material 1.2085:
The steel is generally supplied in a pre-hardened and tempered condition. It has a hardness of approx. 280–325 HB (approx. 950–1100 N/mm²) ex works and does not require further hardening after machining.
It combines good corrosion resistance with excellent machinability.
Very rarely, and mainly for holders or frames. For cutting instruments or instruments used directly on patients, 1.2083 or 1.4112 is generally preferred due to their lower sulfur content and better polishability.
