We can supply bright steel rod after +QT heat treatment.
We supply ground bright steel according to DIN EN 10278 to tolerance class IT 6.
We supply peeled round material according to DIN EN 10278 in tolerance class IT 11 or IT 9. Other tolerances can be supplied upon request.
The first stage, if the material is unfinished, starts with a rough abrasive (perhaps 60 or 80 grit) and each subsequent stage uses a finer abrasive, such as 120, 180, 220/240, 320, 400 and higher grit abrasives, until the desired finish is achieved.
Drawn bright steel is produced from hot-rolled steel bar or wire by chipless drawing.
We supply drawn bright steel in a wide range of cross-sectional shapes according to DIN EN 10278 in tolerance class IT 11 or IT 9.
