NM450 Steel Plate Description
NM450 wear-resistant steel plate is a high-strength structural steel with a nominal hardness of 450HBW, designed for applications where abrasion, impact, and high wear occur.
Thanks to its excellent hardness and toughness balance, NM450 extends the lifespan of equipment components such as mining buckets, dump truck bodies, cement mixers, and crushers.
This material belongs to the GB/T 24186 standard, similar to HARDOX 450 and DILLIDUR 450V, offering great cost performance and easy fabrication through cutting, bending, and welding.
If you are looking for a reliable wear-resistant steel supplier, our NM450 plates are available in customized sizes, thicknesses (6–100mm), and surface treatments.
