NM550 Wear Resistant Steel Alloy
NM550 belongs to domestic wear-resistant steel plate, NM550 steel plate implementation standard: GB/T24186 special technical conditions.
GB= National standard in NM550 steel plate standard
T= recommended in the NM550 steel plate standard
NM550 steel plate standard 24186= Steel plate execution standard number
The NM board series has a total of six brands: NM360, NM400, NM450, NM500, NM550, NM600
NM550 is a representative of high strength structural steel plate. This steel plate has extremely high strength and toughness, and its hardness is very high, so it can be used in a variety of harsh conditions for a long time, including some extreme environmental conditions NM550 steel is a very strong and durable material that can be applied in a variety of harsh environments.
