Hardox 500 questions before buying
What is the equivalent of Hardox 500?
NM500, Rockstar 500, Rockhard 500, IS 18809 ISAR 500 and AR500 are the nearest by hardness. Hardness bands differ slightly: Hardox 500 470–530 HBW to 32 mm, Rockstar 500 450–540 BHN, Rockhard 500 470 BHN minimum, NM500 470–540 HBW.
Can Hardox 500 be cut, bent and welded?
Yes, with care. Wear plate is quenched and tempered, so use the maker's preheat and heat-input limits, low-hydrogen consumables and generous bend radii. Flame or plasma cutting heats the edge; keep cuts cool to avoid softening or cracking.
How do I order Hardox 500 plate?
Give the grade and maker (or "equivalent 500 BHN acceptable"), thickness × width × length, quantity, whether cut-to-size profiles are needed, and the certificate you need (EN 10204 3.1 with hardness results). Brand names are not interchangeable on a drawing unless the buyer approves the alternative.
