What is the difference between Mn13 and Mn18 manganese steel?
Last Updated:
Mn13 (Hadfield manganese steel) has 13% manganese and provides good work-hardening for medium-impact applications. Mn18 has 18% manganese with higher toughness and better work-hardening, ideal for high-impact, high-abrasion conditions such as crusher jaws and mill liners. Choose according to your impact level and wear conditions.
