What is manganese steel?
Manganese steel is a steel alloy containing 11-14% manganese. It鈥檚 often referred to as Hadfield steel, or Hadfield grade, as Sir Robert Hadfield discovered it in 1882. Manganese steel is non-magnetic and is less likely to rust than carbon steel.
What makes manganese steel special?
It has an extremely high impact strength and abrasion resistance in its hardened state. Manganese steel is a steel that works harder the more it鈥檚 used- you can鈥檛 say that 亚博系列全平台入口 a lot of material. In fact, you鈥檒l often hear it described as the 鈥渦ltimate work hardening steel鈥�. Manganese steel is also considered to be an extremely hard material to machine 鈥� it鈥檚 special in that way.
What does “Work Harden” mean?
The steel has self-hardening properties, so the more impact it takes, the harder the material becomes. Think of it as a self-renewing surface. It can achieve up to 3 times its surface hardness during impact without an increase in brittleness. Clifton Steel can pre-peen your manganese steel so it鈥檚 ready 亚博系列全平台入口 service as soon as you get it if that鈥檚 something you need.
What is manganese used 亚博系列全平台入口 in steel?
All steel has manganese in it! It removes oxygen and sulfur when iron ore is converted into iron, and it鈥檚 essential to convert iron into steel. Manganese decreases the brittleness of the steel and adds some toughness.

How do you cut or machine manganese steel?
Super common question about manganese is how to work with it. It鈥檚 not an easy material to machine or weld, it鈥檚 even describe it as having zero machinability. That鈥檚 not exactly the case. The reason it鈥檚 hard to work with is because the material hardens as it鈥檚 cut, so special tools and techniques are required. We鈥檝e been doing this a long time and have the process perfected.

Which is better, manganese steel or carbon steel?
That completely depends on the application. Manganese can reach a hardness score of almost 600 BHN, giving it about 5 times the hardness of mild steel, and almost 3 times the hardness of annealed stainless steel. That sounds great, but sometimes it鈥檚 not what you鈥檙e looking 亚博系列全平台入口 or more than you need.听Talk to a Clifton representative听to find out if manganese is a good material 亚博系列全平台入口 your project.
