What is Mn12 High Manganese Wear Resistant Steel?
Mn12 steel is an austenitic manganese steel, also known as Hadfield steel, that typically contains about 11-14% manganese and about 1% carbon. The high manganese content contributes to the steel’s excellent work-hardening capabilities and outstanding toughness, which increases when used under impact and abrasive conditions.
Key Features
Work Hardening: One of the most notable features of Mn12 wear-resistant steel is its ability to be hardened by machining, rather than heat treatment. When the material deforms under impact or wear, it develops a hardened surface layer while maintaining a tough core.Toughness: Mn12 wear plate has excellent toughness and can withstand severe impact without cracking, making it ideal for heavy-duty applications.Wear resistance: Despite a relatively low initial hardness (around 200 HB), Mn12 steel can reach hardness levels of up to 500 HB on surfaces exposed to wear, extending the service life of parts in abrasive environments.
The unique combination of toughness and wear resistance makes Mn12 high manganese steel suitable for a wide range of applications:
Mining: Used to manufacture components such as crusher hammers, liners and screens that are subject to severe wear.
Construction machinery: Ideal for excavator buckets, bulldozer blades and other earthmoving equipment parts.
Railway industry: Used in railway crossings and turnouts, the material must be able to resist the extreme wear caused by trains passing through.
Agricultural equipment: Suitable for plows, harrows and other farm implements that need to resist soil and crop residues.
