Product Introduction

NM450 is a high-strength wear-resistant steel plate. It has high wear resistance, and its Brinell hardness value reaches 450 (HBW). It is mainly used to provide protection for occasions or parts that require wear resistance, so that the equipment has a longer life, reduces maintenance and downtime caused by maintenance, and correspondingly reduces funds input.

NM450 carbon content generally does not exceed 0.26%, 450 represents the average Brinell hardness of this steel plate.

NM450 has the following general characteristics:

1)High Strength : The yield is over 900, and the tensile strength is over 1180.

2)High mechanical strength: NM450 has quite high mechanical strength, its mechanical properties are 3 to 5 times that of ordinary low-alloy steel plates, it can significantly improve the wear resistance of mechanical-related parts, thus improving the service life of machinery and reducing production costs.

3)High hardness: The surface hardness of this product usually reaches 450-500HB. Applicable structural steel plates for processing and manufacturing wear-resistant and vulnerable parts for mines and various construction machinery.

4)Wide application: NM450 wear-resistant steel plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery, abrasive tools, bearings and other product parts.

NM450 wear-resistant steel plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery, abrasives, bearings and other product parts.

Classification By Size

The length is generally 2440mm, 2000mm, 3050mm, 4000mm, 3000mm, and the thickness is distinguished by cold rolling and hot rolling. Cold rolling mainly has thickness 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm. The main thickness of hot rolling is 3.0mm, 4.0mm, 6.0mm, 8.0mm, 10.0mm, and the width is generally 1000mm, 1219mm, 1500mm.Please contact customer service for general specifications.

Hot-rolled products have excellent properties such as high strength, good toughness, easy processing and good weldability, so they are widely used in manufacturing industries such as steel, construction, machinery, boilers, and pressure vessels. Application range: (1) After annealing, it is processed into ordinary cold rolling; (2) The galvanizing unit with pre-annealing treatment device processes galvanizing; (3) Panels that basically do not need to be processed.

Hot-rolled coils (in the form of flat plates or coils) generally have a thickness of 2.0-13.5mm, of which the price of 2.0-3.0mm hot coils gradually decreases from thin to thick; most steel mills have a basic price of 3.1mm-13.5mm Equivalent, the price of 3.1-4.0mm and 9.5mm-13.5mm hot plate coils in some manufacturers and markets may be higher than the price of 4.0mm-9.5mm plates. Hot plate coils represent products with a thickness of 5.5mm. Under normal circumstances, the price of flat plates is slightly higher than the price of coils.
