WNM360 Wear Resistant Steel Plate

WNM360(NM360) grade is a high-grade quenched and tempered wear-resistant steel plate produced by WuSteel; its grade is low than WNM400 dan NM400.

This standard applies to the quenched and tempered wear-resistant steel plate series with the steel plate thickness not greater than 100mm, and is mainly used for structural steel plates used in the processing and manufacturing of wear-resistant and vulnerable parts for mines and various construction machinery.

China Grade: WNM360

Enterprise Standard: WYJ030-2010

Application: Thickness ≤100mm quenching and tempering wear-resistant steel plate

Composition: manufacturer, purpose, hardness and quality grade

It belongs to the quenched and tempered wear-resistant steel plate produced by Wugang, which implements the enterprise standard WYJ030-2010.

How to express the grade: The grade of steel plate is composed of four parts representing the manufacturer, use, hardness and quality grade in order, for example:
WNM360A, WNM360B, WNM360L, etc.

Symbol: W—represents the first letter of the Chinese pinyin of “Wu” of WuSteel;

NM—the first letter of the Chinese pinyin of the characters “Nai” and “Mo” for wear resistance;

A and B–respectively the quality level, meanwhile, A represents that the steel plate is not impacted, and B represents that the steel plate is impacted at 20 degrees normal temperature;

L–means high weldability steel plate (guarantee wear resistance, reduce carbon equivalent, improve weldability)

Plat keluli menggunakan rolling tepi lurus, kepala dan ekor dipotong, dan dua sisi membujur tidak dipotong, dan margin pemangkasan dikawal mengikut plat pemangkasan biasa.

Baki saiz, bentuk, berat dan sisihan yang dibenarkan bagi plat keluli hendaklah mematuhi GB/T709.

The chemical composition (melting analysis) of WNM360 meets the requirements of the following table:

Gred	C	Dan	Mn	P	S	Mo	Cr	Dalam	B
A	≤0.22	≤0.60	≤1.60	≤0.025	≤0.015	≤0.50	≤1.00	/	≤0.004
B	≤0.22	≤0.60	≤1.60	≤0.025	≤0.015	≤0.50	≤1.00	≤0.60	≤0.004

Note: It is permissible to add microalloy strengthening elements, such as Nb, V, Ti, etc. to the steel plate.

Kaedah peleburan: relau elektrik + penapisan di luar relau.

Delivery status: quenching + tempering = quenching and tempering.
