What is en NM400 steel equivalent steel material
NM400 steel is a kind of abrasion-resistant steel, which has the highest strength among the wear-resistant steel grades at present. This kind of steel is widely used in engineering machinery, mining machinery, coal mining machinery, construction machinery, farming machinery, harbor machinery, excavator and many other industries.
NM400 steel material has superior choice in wear-resistant steel. It has comprehensive mechanical properties, such as high strength, toughness, plasticity, formability, weldability and machinability. The steel also has good corrosion resistance and also it can be quenched and tempered.
NM400 steel has the hardness of 360-440 HBW. Compared with ordinary steel, this kind of steel has superior performance in the aspects of strength, toughness, hardenability, formability, wear resistance, weldability and heat treatment. The characteristic of NM400 steel is high strength and abrasion resistance, which can be up to 5-6 times higher than ordinary carbon steel. At the same time, its hardness and abrasion resistance properties also increase with the increase of hardness (HRC).
The equivalent steel material of NM400 steel is JFE-EH400. The commercial name of JFE-EH400 is JIS EH400 steel. This equivalent material has similar properties with NM400. Its hardness is also between 350HBW-400 HBW. The tensile strength is from 1070MPa to 1300MPa, and the yield strength is from 800MPa to 1100MPa. JFE-EH400 steel has excellent workability and weldability, and it can be used for a variety of structures that require resistance to abrasion, such as grabs, buckets, bulldozers and other equipments.
According to the statistics, NM400 steel and JFE-EH400 steel have been used successfully in over 30 countries. Both of these steel materials have excellent properties of strength and abrasion resistance, and they are widely applied in fields including engineering machinery, mining machinery and artificial landscapes. They have been used in a variety of projects, such as crushing, shovel, bulldozer and excavator buckets.
The main difference between NM400 and JFE-EH400 is that NM400 steel has a little lower tensile strength than JFE-EH400 steel, which also explains why NM400 steel can be more cost-effective than JFE-EH400 steel.
No matter you are using NM400 steel or its equivalent JFE-EH400 steel for machinery parts or structures, you should be aware of their strength and abrasion resistance properties. You should also pay attention to the selection of welding process and the parameters and performances of the heat treatment.
In conclusion, NM400 steel has superior choice in wear-resistant steel, and its equivalent material JFE-EH400 has excellent properties of strength and abrasion resistance, which can be widely applied in engineering machinery, mining machinery, coal mining machinery and other industries. Both of these steel materials have been used to success in a variety of projects and it is important to pay attention to the selection of welding process and the parameters and performances of the heat treatment when using them.
