What is NM450 equivalent ASTM steel
NM450 is an abrasion-resistant steel with a Brinell hardness of 450HBW. It is an economical, general-purpose wear-resistant steel that provides good abrasion resistance in applications such as excavator buckets and rubber liners. It is generally used in applications requiring superior strength and wear resistance.
NM450 is equivalent to ASTM A128 Grade B-3. ASTM A128 is a specification for wear-resistant steel plate developed by American Standards for Testing and Materials (ASTM). It divides wear-resistant steel plates into three grades, depending on the maximum Brinell hardness value of the materials. Grade B-3 is a medium hardness wear-resistant steel material, with a maximum Brinell hardness value of 450HBW (450 on the Brinell Hardness Scale).
NM450 is a low-cost wear-resistant steel, offering superior wear and corrosion resistance than other steel grades in its class. The steel offers excellent weldability and impact resistance due to its high tensile strength and low alloy content. Additionally, its abrasion resistance is superior to that of some high-carbon steels.
NM450 isn’t just a general-purpose wear-resistant steel. As a wear-resistant steel, it provides superior abrasion and impact resistance in demanding, high-abrasive environments. It is commonly used in construction, mining, forestry, and quarrying applications, as well as in the manufacturing of agricultural and forestry equipment.
NM450 can also be used in applications where high wear resistance is needed, such as in die-casting, chemical processing, and food processing. It is also suitable for use in food grade materials and medical implants. Its superior strength and wear resistance make it suitable for use in a variety of industries.
Overall, NM450 is an economical and reliable wear-resistant steel. It is specifically designed to provide superior abrasion and impact resistance in demanding, high-abrasive environments, making it a reliable and cost-effective solution for many industries.
