What is NM450 equivalent ASTM steel
NM450 is a kind of high wear resistant steel used in the manufacture of wear-resistant components imported from Japan. It is equivalent to ASTM A514 steel grade in the United States.
NM450 wear-resistant steel is mainly applied to a variety of engineering structures, such as corrosion-resistant containers and special tools for chemical engineering and metallurgy, as well as bridges, railway vehicles, and offshore structures. This steel also has excellent weldability and is able to withstand low temperature environments.
NM450 is a high-strength wear-resistant steel with an average hardness of 450 HBW. Its properties and quality make it ideal for uses such as crane booms, excavator buckets, construction equipment, and wear plates. According to different hardening methods, NM450 consists of four grades which are NM450-A, NM450-B, NM450-C, and NM450-D.
The ASTM equivalent of NM450 is ASTM A514, which is a high yield strength quenched and tempered alloy steel primarily used in construction machinery. It is equivalent to strength grade 50 of structural steel in the US. It has a minimum yield strength of 100ksi (690 MPa) and can be quenched and tempered to yield a higher strength, such as 110ksi (758 MPa).
The hardness of ASTM A514 is typically quoted as Brinell hardness number (BHN), typically ranging from around 400 BHN up to 650 BHN, depending on the desired application. In comparison to NM450, ASTM A514 has improved mechanical properties and corrosion resistance, making it more suitable for certain applications.
In conclusion, NM450 is a high strength wear-resistant steel with an average hardness of 450 HBW, while ASTM A514 is an equivalent high yield strength quenched and tempered alloy steel primarily used in construction machinery and has a minimum yield strength of 100ksi (690 MPa). Both are noted for their strength and durability, making them ideal for use in a variety of industries, from engineering to production and construction.
