What is en NM500 equivalent astm material
NM500 is an abrasion-resistant steel with a hardness of 500 HBW. NM500 has a very high resistance to wear and excellent impact properties, making it ideal for high-impact and abrasive wear applications. It is commonly used for applications such as crusher liners, chutes, hoppers, and conveyors. Its main characteristics include a high tensile strength and a high toughness.
The equivalent ASTM material for NM500 is ASTM A514. This ASTM material comes in a variety of grades, each with different chemical and mechanical properties. The most common grade of A514 is A514 steel plate. This high strength, low alloy steel plate offers an optimum combination of strength, weldability, and notch toughness. It is typically used in heavy machinery and mining equipment, as well as in other applications where durability and long-term stability are needed.
The primary difference between NM500 steel and A514 steel plate lies in their contents and their different forging methods. NM500 contains Si, Mn and other alloying elements, while A514 contains Si, Mn, Cr and other alloying elements. NM500 is a cold-rolled material resulting from quenching, while A514 is a warm-rolled material hot-rolled and tempered.
A514 steel plate also has higher yield and tensile strengths around 100 ksi and 120 ksi compared to the 50 ksi to 80 ksi yield and tensile strength grades of NM500. A514 steel plate is also air-hardened, making it an excellent choice for applications that require extra strength and toughness. In terms of corrosion resistance, NM500 steel is better than A514 steel, making it ideal for applications that require corrosion protection.
Overall, NM500 offers a variety of benefits specifically related to its abrasion-resistant and hard-wearing nature, while A514 steel plate provides better tensile strength and yield, as well as excellent air hardening properties. Both steels offer their own benefits and can be used in a variety of applications due to their protective nature and strength.
