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 そして 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)

スチールプレートはまっすぐなエッジローリングを採用し、頭と尾が切断され、2つの縦方向の辺が切断されず、トリミングマージンは通常のトリミングプレートに従って制御されます。

鋼板の残りのサイズ、形状、重量、許容偏差は、GB/T709に準拠するものとします。

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