Product Introduction

NM400 steel plate, also universally recognized as abrasion-resistant steel plate, is a high-strength wear-resistant steel material compliant with GB/T24186 Chinese standard. It features exceptional wear resistance, outstanding structural strength and stable mechanical performance, effectively enhancing the anti-wear capability of heavy mechanical components.

Compared with ordinary carbon steel and low-alloy steel, the comprehensive mechanical properties of NM400 steel are 3 to 5 times higher. Excellent wear resistance greatly extends the service life of equipment parts, reduces frequent replacement and maintenance costs, and ultimately lowers the overall production cost for industrial enterprises. Benefiting from its superior performance, NM400 steel plates are widely adopted in various heavy-duty commercial and industrial fields.

1.Mechnical property for NM400 Abrasion resistance steel
NM400 steel delivers balanced high strength, toughness and ductility, with stable mechanical indicators suitable for long-term heavy-load and wear working conditions. The detailed mechanical property parameters are as follows:

Tensile strength (≥Mpa)	-20℃ impacting test absorbed energy (Longi.J)	Elongation in ≥,%	HBW
1200	≥24	50mm	370-430
		10

2.Chemical composition for NM400 Abrasion resistance steel (Heat Analysis Max%)
The precise chemical composition ratio endows NM400 steel with excellent wear resistance, hardness and weldability. Strict component control ensures consistent batch stability and reliable service performance. The chemical composition standards are shown below:

Element	Content (Max %)	Element	Content Standard
C	0.3	Mo	0.50 Max
Si	0.7	Ti	0.050 Max
Mn	1.6	B (Total)	0.0005-0.006
P	0.025	Als (Min)	0.010 Min
S	0.01	Ni	0.70 Max
Cr	1	-	-

3.NM400 Steel Equivalent Grades
For global project procurement and standard matching, NM400 wear-resistant steel has multiple equivalent grades in international mainstream standards (ASTM, EN, DIN, Indian Standard). These equivalent grades share similar hardness, wear resistance and mechanical performance with NM400, which can be used as alternative materials for cross-standard engineering projects. The detailed equivalent grade comparison is as follows:

Standard System	Equivalent Grade
American ASTM	AR400
German DIN	DILLIDUR 400V
European EN	S460
Indian Standard	IS 2062 E450 BR/D
SAE Standard	SAE J434 Grade D

Note: Although the above grades are equivalent to NM400 in core performance, there are slight differences in chemical composition and process performance. It is recommended to confirm processing and welding parameters according to actual project requirements before material replacement.

With high speed development of technology and modern industry,manufactures are more likely to use high strength abrasion resistance steel plates so as to reduce the economic lost brought by part wear.NM400 under GB/T24186 are mainly used for charging cranes,excavators,dumpers,conveyers,trucks,breaking and cutting tools,waste disposal and recovery equipments.
