NM450 equivalent grades

– Hadfield Manganese Steel Hadfield Manganese Steel is an alloy steel usually containing around 1.2% - 1.65% carbon, 12% - 14% manganese and small amounts of silicon, phosphorous and sulfur. It is widely used in a variety of structural and mechanical engineering applications including power transmission Towers, locomotive, and shipbuilding. This bolt is relatively soft and easily formable, however its strength and hardness increases when it is exposed to air.
    
    The grade of Hadfield Manganese Steel was first developed in 1882 by Robert Hadfield. He had discovered that the addition of manganese to steel significantly increased its strength and hardness when exposed to air. Today, this low-carbon alloy is still commonly used for industrial applications due to its excellent combination of mechanical properties and its resistance to wear and corrosion.
    
    Hadfield Manganese Steel is also known as ‘Manganese Steel’, ‘Manganese’, or ‘Hadfield Alloy’ and is often referred to by its NM450 material strength rating. This grade of steel is particularly popular amongst industrial and off-shore shipping applications as it has excellent resistance to wear and corrosion resulting in a reduced need for component replacements, repairs and downtime. Furthermore, NM450 steel is also easily shaped and formed into components with very tight tolerances.
    
    The most common application of Hadfield Manganese Steel is in the form of crusher parts. The high manganese content of the steel results in an excellent wear resistance allowing these components to perform longer and require fewer replacements. Another popular application of NM450 steel is in the form of wear plates used to protect other steel components against wear and abrasion. This is particularly useful for large industrial machines, where the wear plates can significantly reduce the need for maintenance and component replacements.
    
    In conclusion, Hadfield Manganese Steel (NM450) is an excellent grade of steel that has a high manganese content, making it ideal for industrial applications that require wear and corrosion resistance. It is also easily formed, highly durable and economical. It is commonly used for applications such as power transmission towers, railway carriages, off-shore shipping and crusher parts.
