What is NM450 equivalent Indian standard
NM450 steel plates are used for structures and components requiring superior abrasion resistant properties. The steel plates are used for vehicles, bridges, towers and other structures. The alloy steel plates are used for making parts that are subject to high wear and tear.
In India, NM450 steel plates are known as ‘RAMOR 450’ or ‘450HB’. It is an abbreviation for ‘RAcer'S MuScle with Re-Heat TreaTment’. It is the equivalent of Indian standard (IS) grade IS 2062 E450 BR. This grade has been introduced by the Bureau of Indian Standards (BIS). It is similar to the European material designation EN 10025 S460.
NM450 steel plates are primarily used in components like crushers, cement grinders and other engineering components. These plates are used in various fabrication processes like welding, bending and cutting. The wear resistant property of these plates helps them survive in tough terrains and even gives them an edge in racing situations.
NM450 steel plates have superior properties such as high strength and excellent wear resistance. The chemical composition of NM450 steel plates include C- 0.24, Mn-1.50, Si- 0.55, P- 0.030, S- 0.015, Cr- 0.50, Ni- 2.00 and N- 0.010. The mechanical properties of this steel are as follows. The Ultimate Tensile Strength of these plates is about 770 MPa, Yield Strength of 420 MPa and Elongation of 17%.
The hardness of NM450 steel plates is about 450HB (Brinell Scale). If a comparison is to be drawn, then IS 2062 E450 BR is comparable to NM450 steel plates. It has a 482MPa tensile strength, a 345MPa yield strength and an 18% elongation. The hardness (HBW) of IS 2062 E450 BR is approximately 224 HBW. This grade of steel plates is also quite suitable for forming, rolling and pressing operations.
NM450 steel plates are used in various industries such as Plastic, Petroleum and Chemical Industries. This grade of steel plates is also suitable for being flame-cut and plasma cut. With the superior wear resistant properties it offers, it is widely used for mining and quarrying applications. It is highly suitable for automobile parts and steel constructions of bridges.
In conclusion, NM450 steel plates are superior quality wear resistant alloy steel plates that are preferred in a wide range of applications like mining, quarrying, automotive, construction, for vehicles and bridges. Its Indian equivalent, Grade IS 2062 E450 BR, offers excellent wear resistance and superior strength. NM450 steel plates have superior mechanical and chemical properties as compared to other grades of steel plates.
