NM360 (GB/T 24186) questions before buying
What is the equivalent of NM360?
Nearest are 360 BHN mill grades; IS 18809 starts at ISAR 400. Chinese mills may add their own brand name; check the mill data sheet and certificate.
Can NM360 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 NM360 plate?
Give the grade and maker (or "equivalent 360 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.
