What is the NM500 vs nm 400 size range?
The NM500 and NM400 are two steel grade materials manufactured and supplied by the Nippon Steel Corporation, one of the largest steel companies in the world and a leader in steel production. The NM500 and NM400 are high strength, abrasion-resistant grades of steel generally used in a variety of parts and components that require superior wear-resistance to common carbon steel, such as mining equipment, truck beds and construction machinery.
NM stands for Nippon Metallic and the code associated with each grade designates the pressure strength, yield strength, tensile strength and impact toughness in descending order. The numerical codes are established by the Japanese Industrial Standards Organization (JIS). The NM500 and NM400 steel grades belong to the classification of wear-resistant steels.
The components made with NM500 and NM400 steel grades have an excellent combination of superior pressure strength, high yield strength, and high wear-resistance. These steel grades are suitable for applications used under harsh circumstances and mechanical surfaces that experience abrasion, such as crushers, buckets, diggers, and hoppers.
The main distinguishing features between the NM500 and NM400 steel grades is their size range. The NM500 has a size range from 0.8mm to 100mm, whereas the NM400 has a size range from 4mm to 80mm. In addition, the NM500 is more wear-resistant than the NM400, owing to its larger size range.
Both the NM500 and the NM400 steel grades offer superior corrosion-resistance and superior heat-resistance. They are also highly weldable, machinable and drillable. In terms of weight, the NM500 is slightly heavier than the NM400 when compared over the same size range.
The two steel grades can be further divided into two different types: hot rolled and cold rolled. The hot rolled grades have a better surface finish, offer greater strength and have a higher tensile strength than the cold rolled grades. In addition, the hot rolled grades are more malleable and deformable than the cold rolled grades.
The NM500 and NM400 steel grades are widely used in parts and components of excavators, shovels, bulldozers and buckets. They are also used to make parts for construction equipment, tanks and vehicles, such as cranes and trailers.
Overall, the NM500 and NM400 steel grades are the two most popular steel grades manufactured and supplied by Nippon Steel Corporation. The NM500 has a wider size range than the NM400 and can withstand greater wear-resistance, making it an ideal choice for applications that require superior wear-resistance. Both steel grades offer excellent corrosion-resistance and heat-resistance and are highly weldable and machinable. Thus, they are an ideal choice for parts and components that experience high levels of wear and abrasion and must remain strong and durable for years to come.
