Titus Manganese Steel (Manganal)
The Ultimate Work Hardening Manganese Steel (11-14% MN / 1% C)
General Information
TITUS Manganese Steel (TITUS Mn, Manganal) is a “Work Hardening” steel commonly referred to as “AUSTENITIC 11-14% Manganese”. Titus Mn is produced to the original “Hadfield Specification” which guarantees optimum wear and work hardening properties. Our manganese steel is also “non-magnetic”.
Manganese Steel Advantages
WORK HARDENING refers to the fact that the steel becomes harder and harder the more it is impacted or compressed.
The “Hadfield” grade has an original hardness of approximately 220 Brinell. With continued impact and /or compression, it will surface harden to over 550 Brinell.
It should be noted that only the outer skin surface hardens. The under layer remains highly ductile and tough. As the surface wears, it continually renews itself, becoming harder and harder.
Manganese Steel (Manganal) is an austenitic steel which means it is non-magnetic. This property makes it useful in many applications such as bottom plates for lifting magnets, separator drum shells for magnetic materials, wear shoes on electric brakes, etc.
