NM400 is a kind of high strength wear-resistant steel plate

Nomenclature and properties of NM400 steel plate

Naming: N stands for "nai", M stands for "grind" (mo), which is the first pinyin letter of the two Chinese characters for wear resistance, and 400 represents the average Brinell hardness of this steel plate.

 

Properties: Steel plate, high strength wear-resistant steel plate.

 

Chemical composition and mechanical properties of NM400 steel plate

 

Chemical composition: The chemical composition of NM400 includes carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P), and other possible alloying elements such as chromium (Cr), molybdenum (Mo), etc. The specific chemical content will vary according to the manufacturer's internal control standards.

 

Mechanical properties:

 

Yield strength: usually above 900MPa, and some data indicate that its yield strength can exceed 1000MPa.

 

Tensile strength: above 1100MPa, some data indicate that its tensile strength can reach 1200MPa or higher.

 

Hardness: The surface hardness usually reaches 360450HB, and some domestic NM400 hardness ranges in 360420HB.

 

Impact performance: NM400 wear-resistant steel plate also has good impact performance and can maintain stability in complex working environments.

 

NM400 steel sheet delivery status and specifications

 

Delivery state: usually tempering state, that is, quenching and tempering treatment, to obtain the best mechanical properties and wear resistance.

 

Specifications: NM400 wear-resistant steel is available in a variety of sizes, including different thicknesses, widths and lengths. Common thicknesses range from 8mm to 75mm, with widths and lengths tailored to specific needs.

 

NM400 steel plate application range

 

NM400 wear-resistant steel is widely used in a variety of occasions requiring wear resistance and high impact loads, such as:

 

Mining machinery: used in the manufacture of crushers, vibration screens, loaders, excavators and other equipment wear-resistant parts.

 

Coal mine machinery: used to manufacture coal machine teeth, scraper conveyor and other equipment wear-resistant parts.

 

Environmental protection machinery: used to manufacture a variety of wear-resistant structural parts.

 

Construction machinery: Used in the manufacture of bulldozer bucket, knife plate, scraper transport, dump truck and other equipment wear-resistant parts.

 

Other fields: It can also be used to manufacture wear-resistant parts in metallurgical machinery, chemical machinery, electric machinery and other fields.

 

NM400 steel plate features and advantages

 

High strength: the yield strength and tensile strength of NM400 wear-resistant steel plate are much higher than that of ordinary low-alloy steel plate, which can withstand greater load and impact.

 

High wear resistance: Through special alloying elements and preparation process, NM400 wear-resistant steel plate has excellent wear resistance, which can effectively extend the service life of the equipment.

 

Good processing performance: NM400 wear-resistant steel plate has good machinability, can be cut, welding, drilling and other processing operations, easy to process and install in the production process.

 

Corrosion resistance: After special anti-corrosion treatment, NM400 wear-resistant steel can be used in a variety of harsh environmental conditions, effectively reducing equipment maintenance costs.
