What is NM450 equivalent British standard
The European equivalent of NM450 steel is the British Standard BS75D. NM450 steel is a heat treated and quenched and tempered (Q&T) steel that is used primarily in the automotive, mining and construction industry. This type of steel is gaining popularity due to its exceptional wear resistance and good machinability characteristics.
BS75D is one of the grades of alloy steel that complies with the British Standard BS EN 10025-2. It is a high tensile steel of medium strength, and is made up of carbon, manganese, silicon, phosphorus and sulfur. BS75D is also know as structural steel grade 43D and can be referred to as D43D. It has become a popular choice for construction and engineering projects in the UK due to its strength and durability characteristics.
NM450 is an excellent wear resistance steel, which has a relatively high strength, good toughness and ductility, and good resistance to wear corrosion. Its wear-resistant performance is superior to BA steel, making it more suitable for customer application areas that require wear-resistant properties. It is mainly used as a wear-resistant liner for construction, mining, tunnel excavation and other related industries where wear resistance and long life are important factors.
In comparison to NM450 steel, BS75D is also used in applications that require high strength, such as mechanical components and machine tools. It is also used in the manufacture of pipes, plates, fasteners and pressure vessels. BS75D has high tensile strength, good weldability and excellent machinability properties, making it a popular choice for many industrial projects.
In conclusion, NM450 and BS75D are both high strength and wear resistance steels that are suitable for a variety of engineering applications. Both steels have excellent strength, good toughness, and excellent machinability properties that make them a popular choice for many industrial projects. Depending on the application area, one or the other steel may be more suitable.
