NM500 Grade equivalent
The NM500 grade is a martensitic wear-resistant steel plate that has a hardness of 500HBN as measured on the Brinell Hardness Scale. This grade of steel is highly sought after in the manufacturing industry due to its strength and resilience to wear and abrasion. The NM500 grade offers outstanding performance in the most demanding of environments, given its enhanced properties such as high tensile strength, tremendous fatigue strength, excellent toughness, and superb weldability.
The NM500 grade can withstand temperatures of up to 500 degrees Celsius and its outstanding wear resistance is ideal for both cutting and impact applications. It is also an ideal choice for components that are exposed to harsh environments, such as those found in the mining and construction industries. When manufacturing components with the NM500 grade, it offers excellent machinability and is suitable for applications requiring stepped components and/or complicated shapes.
In comparison to other wear-resistant steel plates, the NM500 grade is much stronger than the previously used NM400, making it an ideal choice for high-stress applications. Furthermore, the NM500 grade offers comparable performance to the conventional 750 grade, except that the latter is much more costly due to its higher milling and alloying costs, while the NM500 display better wear resistance and damage tolerance compared to the 750 grade.
When it comes to machining, the NM500 grade provides excellent performance, tolerance and finish quality. Its wear-resistant properties are also enhanced after heat treatment, becoming even more durable. The NM500 grade is also quite popular among artisans due to its positive qualities when used in crafting of knives, tools, and other applications requiring wear-resistant material.
In conclusion, the NM500 grade is an excelling choice when strong and wear-resistant properties are desired from a steel plate. Its comparable performance to the 750 grade, combined with its cost-effectiveness and superior machinability and weldability make it an ideal choice for a broad range of applications across many industries.
