Thread: Bartmaan Manganese Steel.question

Edit: Here is a blurb I found on Wikipedia

Mangalloy is made by alloying steel, containing 0.8 to 1.25% carbon, with 11 to 15% manganese.[1] Mangalloy is a unique non-magnetic steel with extreme anti-wear properties. The material is very resistant to abrasion and will achieve up three times its surface hardness during conditions of impact, without any increase in brittleness which is usually associated with hardness.[2] This allows mangalloy to retain its toughness.

Most steels contain 0.15 to 0.8% manganese. High strength alloys often contain 1 to 1.8% manganese.[3] At about 1.5% manganese content, the steel becomes brittle, and this trait increases until about 4 to 5% manganese content is reached. At this point, the steel will pulverize at the strike of a hammer. Further increase in the manganese content will increase both hardness and ductility. At around 10% manganese content the steel will remain in its austenite form at room temperature.[4] Both hardness and ductility reach their highest points around 12%, depending on other alloying agents.[1]
