Supplied material

The material is delivered in annealed condition.
There may be scale or surface corrosion on the surface.
Some material may be descaled by sandblasting at the factory.
Depending on the production technology, the material may not be perfectly flat.
Microcracks may appear on the surface of the material from production, so it is recommended to sand off approx. 0.1 - 0.15 mm from the top layer.

Dimensional tolerances

Material diameter tolerance: +/- 1.0 mm
Material length tolerance: +/- 3.0 mm
