What is the NM450 vs NM400 size range?
The NM450 vs NM400 size range can be a confusing comparison to make. Depending on the specific application or project, there could be many different considerations to make when choosing between the two sizes. Depending on the end use, designers must decide whether the NM450 or NM400 more suitable size option.
NM450 steel is a structural steel grade with a carbon content of less than 0.3%, which makes it suitable for welding and metal forming. Its tensile strength and yield strength are higher than those of NM400 steel. Its yield strength is about 465Mpa and sharp tensile strength is between 700 - 1050Mpa. The NM450 is a typical abrasion resistant steel material with a high hardness; its hardness approaching to 500HBW. It has excellent abrasion resistant property suitable for various applications where abrasive strength is required.
NM400 steel is a hard and wear-resistant steel due to its special chemical composition and properties. It has a high manganese content of more than 3.5% at a maximum and its maximum tensile strength is 1300 MPa. With its excellent properties such as strength, toughness, wear resistance, and high temperature resistance, NM400 steel is widely used in various types of industrial applications such as mining and construction materials, petrochemical and engineering industries. The NM400 steel has good formability and weldability and can also be easily machined.
The two types of steel offer similar strength and wear resistance, but there are a few important differences between the two. One of the primary differences between the NM400 and NM450 is the thickness of the material available for each. While NM400 has a thickness of up to 50mm, NM450 has a thickness of up to 100mm. The NM450 is also harder than the NM400 and is generally used in applications where hardness is a priority.
The NM450 is also considered the better choice for thicker wear parts, as it can withstand more wear and tear. This makes NM450 a more suitable option for projects that involve heavy-duty wear items such as an excavator blade or bulldozer blade.
When it comes to price, NM400 steel also has an advantage over NM450. As NM450 steel has a higher manganese content, it is more expensive than NM400. Furthermore, the NM450 is more difficult to cold form, resulting in increased labor costs. Additionally, NM400 steel can be more readily available than NM450, which could lead to cost savings in certain projects.
When choosing between the two, it is important to consider the application at hand and determine which is more appropriate for the project. NM400 steel is suitable for minor abrasion applications such as automotive parts, machinery parts, and agricultural tools, while NM450 is better for complicated and heavy-duty applications such as digging machines and bulldozers.
In conclusion, the NM450 vs NM400 size range can be a difficult comparison to make. Depending on the specific application or project, the designer must decide whether the NM450 or NM400 more suitable size option. In general, the NM400 is more economical and suitable for lighter wear parts and applications, while the NM450 is more suitable for thicker and heavier wear parts.
