nm500 vs ar500
-AR500 steel, also known as 500 BHN (Brinell Hardness) and NM 500, is a type of abrasion-resistant steel which has been heat treated and quenched and tempered to greatly increase its hardness and strength. The AR500 steel alloy is popularly used in the construction and defense industries and is a great choice for applications that require a combination of durability and performance.
NM500 is a high-strength wear-resistant steel plate that is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product components. NM500 has high wear resistance and good impact performance. It can be cut, bent, and welded like ordinary steel plate, so it can be easily processed into various shapes and sizes and can be used to manufacture wear-resistant structures with high performance and long service life.
Both AR500 and NM500 are high-strength, wear-resistant steel plates, but AR500 is considered to be more abrasion resistant than NM500. Both steels are heat treated and quenched to gain their hardness and strength, resulting in a harder surface for fabrication that is suitable for many applications. What sets AR500 apart, however, is its higher hardness of 500 Brinell, compared to NM500, which has a Brinell Hardness of 370-430, making AR500 much more wear-resistant. AR500 is also greater in tensile strength, while both materials have similar yield strengths.
Given the higher hardness and tensile strength, AR500 is best used for applications such as ballistic armor, and heavier wear plates, while NM500 has better resistance to mid and low level abrasion and impact resistance for lighter applications, and can be used for items such as liners, chutes, and crushers. In addition, NM500 offers superior weldability compared to AR500 steel.
In conclusion, AR500 and NM500 are both high-strength, wear-resistant steel plates that offer good performance and durability. The decision of which to choose should be based on the application and the intended use.
