Need Help!- Laser cutting abro400/hardox400

[sheffcruiser]

Anyone have any experience cutting this? Especially on a Trumpf Laser?

Thanks

IIRC... o2 pressure and speed had to drop. Hardox cuts like A36 but is real fussy. Prone to "blowout" - cutting alone fine, then hits a patch of ???? and flares. Balance the settings right an it will cut nice and consistant. Sorry I can't give you any settings.

Hi.
We are cutting this sometimes. 15mm cut on default parameters, just a little bit slower, if doesn't want to cut nice - use bigger nozzle (not too big.. 1.7 instead of 1.4 is enough) if u use bigger nozzle u can lower gas pressure. It is not more difficult then any other mild steel... problem is when it is too rusty or not clean...hardox is ok, cor-ten is pain in ass
