Manganese Steel - 6 Things You Need to Know | AJ Marshall

Many of mangalloy's uses are often limited by its difficulty in machining; sometimes described as having "zero machinability." The metal cannot be softened by annealing and hardens rapidly under cutting and grinding tools, usually requiring special tooling to machine. The material can be drilled with extreme difficulty using diamond or carbide.
