NM550 steel -hot rolled wear resistant steel plate pdf

1.What is NM 550 steel?

NM550 Steel: An Abrasion Resistant Steel with 550HB

NM550:

Hardness: 520-570 HBW

Abrasion Resistance: Further enhanced hardness and abrasion resistance compared to previous grades, suitable for extremely demanding wear applications.

NM550 steel is one kind of Chinese wear/abrasion resistant steel plates.NM500 Sheet Steel is one steel grade in GB standard GB 24186. NM 500 steel is a high-strength, wear-resistant / abrasion resistant steel known for its superior hardness and durability. This steel is specifically designed to withstand high wear conditions and provide extended service life in challenging environments.

nm550 was hot rolled and then the plates were heat-treated by direct quenching and tempering and reheat quenching and tempering techniques, respectively. With high mechanical strength, NM550 is 3 times to 5 times more than common low-alloy steel plates which can significantly improve surface hardness, usually achieved 360 ~ 450HB.

2.NM550 Steel Form of Supply

NM550 steel, we can supply the steel flat bar and plate Rectangular pieces can be sawn from flat bar or plate to your specific sizes.

NM550 Wear Steel Plate Product Parameters

NM550 steel wear resistant plate ensures unbeatable performance, savings and enhanced lifetime for your equipment. Weather you are looking to loose weight or gain strength in applications such as truck bodies, dumper bodies, containers and buckets or if you need production wear parts that simply outlast other materials, NM550 is the best choice.

The outstanding performance characteristics of NM550 wear plate come from a combination of hardness, strength and toughness. As a result nm550 can stand up to sliding, impact and squeezing wear. Nm550 goes beyond wear resistance, allowing you to protect your equipment investment and work more effectively.

In truck bodies and containers, NM550 ensures a longer lifetime and highly predictable performance. Its high strength and hardness often allows for a thinner plate, enabling a higher payload and better fuel economy.

NM550 in your bucket translates to a longer equipment lifetime and enhanced reliability thanks to outstanding wear and deformation resistance. Enhanced performance is achieved because NM550's wear resistant properties are evenly distributed across the plate.

3.NM550 Steel Application

The series of NM wear-resistant steel combined the properties including high strength, high hardness, high wear resistant, weldable, bendable and mainly applied in:

Edge of loaders in loader industry

Wear-resistant lining plate in crusher industry.

Slat type conveyer in colliery mechanical industry.

Lining plate of coal pulverizer in power industry.

Lining plate of hopper for heavy handling truck.

what is NM550 steel equivalent to?

NM550 steel is equivalent to other wear-resistant steels such as Harox 550 produced by SSAB of Sweden and EH550 from Japan, all of which have similar mechanical properties and are used in similar applications.

What is the difference between AR500 and NM500 steel?

Key implication: AR500 is preferred in North America for compliance with ASTM certifications, while NM500 dominates Asian markets . Both steels exceed 500 HBW surface hardness, but AR500 shows marginally higher tensile/yield strength and better low-temperature toughness .

What is the hardness of NM 500?

With a hardness range of 470-540 HBW, NM500 is widely used in applications where resistance to abrasion is a primary concern, such as in mining equipment, construction machinery, and other heavy-duty applications.

Is AR550 stronger than AR500?

Higher hardness: AR550 steel measures closer to 550 BHN, offering better resistance to deformation and pitting. Improved performance with high-velocity rounds: AR550 withstands repeated impacts from 5.56 and . 308 much better than AR500.
