What is the NM400 vs NM450 size range?

    
    The NM400 and NM450 are two types of abrasion-resistant steel plates that are commonly used in industrial applications. Both steel plates are known for their strength and durability, providing hard-working professionals with the materials needed to get their job done.
    
    NM400 is a high-strength wear-resistant steel plate that is made from alloyed steel with a hardness of 400 HBW (Brinell hardness). It is also known for its excellent mechanical properties, exhibiting very good resistance to impact and abrasion. The steel plate has a yield strength of 420MPa, a tensile strength of 520 MPa, and an elongation of 17%. The hardness of NM400 increases with temperature, which allows the steel to retain its shape and form in extreme temperature conditions.
    
    NM450 is also a high-strength wear-resistant steel plate that is made from alloyed steel with a hardness of 450 HBW (Brinell hardness). This steel plate has a yield strength of 560MPa, a tensile strength of 770 MPa, and an elongation of 17%. NM450 exhibits very good resistance to corrosion and corrosion fatigue. Additionally, the hardness of NM450 increases with temperature, giving the steel plate the ability to maintain its shape and form in extreme temperature conditions.
    
    The size range of NM400 steel plates is typically from 4mm to 40mm in thickness. The range of sizes available for NM450 steel plates is typically from 4mm to 50mm in thickness. The range of size for NM400 and NM450 steel plates can vary depending on the manufacturer and the application for which the steel plates are meant for.
    
    The differences between NM400 and NM450 steel plates can vary depending on the application for which they are meant for. For example, NM400 steel plates are used in applications demanding an economical yet excellent and reliable wear-resistant steel plate. Examples of these applications can include workers trampling over equipment, punching, drilling and tooling metals.
    
    On the other hand, NM450 steel plates are used in more extreme applications, such as mining operations and earthmoving machinery. Examples of these more extreme applications can include high impact, abrasion and mechanical damage.
    
    The NM400 and NM450 steel plates both possess exceptional qualities that make them ideal for different types of applications. NM400 steel plates can provide excellent strength and durability for an economical price, whereas NM450 steel plates can deliver unparalleled strength and durability for more extreme applications. Therefore, depending on the needs of the application, the NM400 or NM450 steel plate may be the more suitable choice.
