GB NM400 HB400 AR400 Wear-resisting Steel Plate

1: NM400 Steel Introduction

NM400 steel has high mechanical strength, and its mechanical properties are three to five times higher than those of ordinary low-alloy steel plates, significantly improving the wear resistance of machinery-related parts, thus extending the service life of machinery and reducing production costs. Its surface hardness usually reaches 360 ~ 450HB, hardness values range from 360-420HB.

11: NM400 Steel Heat Treatment

Quenching

NM400 steel is heated to 880-920 degrees Celsius and then subjected to a rapid cooling process, such as water quenching or oil quenching, to obtain high hardness and excellent wear resistance. The quenched material is usually brittle and therefore requires subsequent tempering to improve its overall properties.

Tempering

Carried out after quenching, the steel is heated and held to obtain the required hardness, toughness and other mechanical properties. The tempering temperature is generally between 200-300 degrees Celsius, and the holding time is related to the thickness of the plate. Tempering can significantly improve the toughness and resistance to deformation of the material, while reducing the hardness.

12: NM400 Steel Application

NM400 steel plate is widely used in the manufacture of wear-resistant parts for mining, engineering machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other equipment. For example, it is commonly used in bucket plates, edge plates, side edge plates, blades of excavators, loaders, bulldozers, as well as crusher liners and blades, etc.

13: Delivery Condition

For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed or QT, black surface or rough turned.
For hot forged plate, usually the delivery condition is hot forged, annealed or QT, milled surface.
For hot rolled plate, usually the delivery condition is hot rolled, annealed or QT, black surface.
