High Manganese Steel AG Mill Liners

Mill Type: AG Mill
Hardness: HB310-400
Surface Finish: Ra100
Size Tolerance: as per CT13
Application: AG Mill / SAG Mill
Material: Cr Mo Alloy Steel, High Manganese Steel
Microstructure: Pearlitical
Hardness: HRC32-56
Material Grade: AS2074 L2A,L2B, L2C
Production Process: Sand Cast Process + Normalizing + Tempering
Melting Process:Induction Melting
Impact value:about 60J without nortch test bar

Wear Performance: 20% increase in comparison with ASTM A128 Grade C under same working condition.

High wear resistance and impact resistance:

High manganese steel liner has scientific and reasonable alloy element formula, so that the liner has good physical and chemical properties. The hardness is above HRC45-55, the impact toughness value is above 25J, and the service life is more than twice that of high manganese steel. Able to withstand huge impacts. The surface shape of the liner can be maintained for a long time during work to ensure that the mill can increase the output by more than 5%
