What is en NM450 equivalent steel material
NM450 steel is a Chinese abrasion resistant steel which is comparable to Hardox450. NM450 is a type of wear-resistant steel with high strength and good impact toughness. It is developed on the basis of conventional high-strength materials. It has both high wear resistance and good impact performance, which can meet the requirements of wear resistance and have certain impact performance. The combination of wear resistance and impact toughness makes it have a wide range of applications.
NM450 steel is a kind of wear-resistant steel, which has abrasion resistace (wet and dry)≥450, average impact energy value≥25J, hardness 230 HBW. It is suitable for many applications. It is usually used to protect welding points in the construction and mining industries, while also being used in chemical and food industries.
NM450 steel has excellent weldability, so it is often used in a variety of cold welding, such as chemical equipment and household appliances. The characteristics of NM450 steel, such as wear-resistance and corrosion-resistance, are important, and it is an important material for many industrial applications, such as mining machinery and engineering structures.
The equivalent grade of NM450 steel in the US is called Hardox450. Hardox450 is renowned for its self-lubricating ability and wear-resistance, with a hardness of 450hb est. It is a wear-resistant steel wear plate that's highly resistant to abrasion and offers even wear pattern. Hardox450 provides a unique balance of strength, flexibility, and above-average impact resistance, and it is one of the most commonly used wear-resistant steels in Europe.
Hardox450 is extremely resistant to abrasion, with a nominal hardness value of 450HBW. It has the same wear-resistance as NM450 and better weldability, with a minimum yield strength of 550 MPa and an ultimate tensile strength of 960 MPa. The impact toughness is good, with an average impact energy value of 25J.
Hardox450 is suitable for cold processing, welding, flame cutting and providing enhanced wear-resistance in tumbler/ vibratory container. It is often used in crushers, chutes, hoppers, flue ducts, and other aggregate processing machinery. It is used to protect wear-resistance parts of excavators, bulldozers, scrapers, and so on. It is also used in the lining of conveyor buckets, hoppers, bins and tipper bodies. It can also be used for barrels, feeders, and other fixturing applications.
Both Hardox450 and NM450 steel have excellent wear resistance and good impact toughness. They have different chemical compositions and toughness, but are comparable when it comes to their usage and capabilities. Both materials are suitable for the same applications and provide impressive wear protection, suitable for working under high loads, and for instances where high shock or impact situations are expected. Therefore, Hardox450 and NM450 steel are equivalent materials, and both are suitable for various wear protection applications.
