Processing
Polishing: The polishing of material grade 1.2083 is possible in soft annealed and hardened condition. In this case, a good preparation of the surfaces is decisive for a good polish.
Etching: Good photo etching is given. (Scar)
Erosion: In the hardened and tempered state, the material 1.2083 can be eroded. Afterwards, it is necessary to depressurize again approx. 20°C below the last tempering temperature.
Nitriding and hard chrome plating is not common with this material.

Heat treatment 1.2083
Low-stress annealing: A temperature between 600°C and 650°C should be considered for stress-relieving annealing. Thereafter, a furnace cooling takes place.
Soft annealing: The material 1.2083 should be soft annealed at temperatures of 760°C - 800°C. Subsequently, a slow cooling in the oven must be done.
Hardening: Hardening takes place at 1000°C - 1050°C. This is followed by cooling in air, oil or in a warm bath.

Sägeszuschnitt
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 1.2083:
In the hardened and tempered condition, the material typically achieves a hardness of approx. 53 to 56 HRC.
No, the weldability of 1.2083 is considered poor due to its high carbon and chromium content.
ESR stands for Electroslag Remelting. This special grade is extremely pure, contains very few inclusions and allows mirror-like polishing without "breakouts".
