Our large range of alloys and our ability to cast to specification means your wear parts will not only last longer, they will do a better job too.
Choosing the right raw materials and determining the right % of manganese for the hardness or toughness of the product required takes skill and scientific ability.
Our Lab and team of scientists help us to manage the alloy selection
Manganese wear parts are sold in 3 common grades, 14% (Hadfield manganese), 18% and 21+% grades. 14% manganese has been used in crushing around the world for over 100 years and is a very reliable material for crusher liners. 14% manganese is supplied from the foundry with a hardness of approx 200 Brinel (HB), and when crushing rock with a high compressive strength (hard rock), will work harden to 450-500HB.
We use the following alloys:-
All parts are cast in Hadfield manganese with a 2% chromium addition – a process proven to provide some of the best wear profiles to date, dollar for dollar.
Custom heat treatment depending on section thickness
Salt water quench for greater carbide precipitation in Mn
FSF continues to research various ranges of manganese content and altered heat treating combinations to better serve our customers’ needs.
