Mn13 manganese steel is the best choice for resist-high impact ,the material of big stress in wear resistance.The high manganese steel have two biggest features: one is external impact more bigger ,the wear-resistance of appearance is more higher ; another is with the gradually abrasion of densified laminated appearance, new densified laminated process is formed continually.
