Choosing a Quality Meehanite Foundry Assures that Your Casting Meets or Exceeds Customer Expectations!
Meehanite Wear and Abrasion Resisting Types (Almanite®)
Type W is a series of austenitic-martensitic white irons characterized by high hardness and relatively good impact strength. Type W has a pearlitic matrix; Type W2 has a martensitic matrix; Type W4 is highly alloyed to provide an austentic matrix in the as-cast condition which may be further modified to give a martensitic matrix by heat treatment or by freezing.Type WS is a hard wearing martensitic iron with exceptional impact strength...not readily machinable... work hardens in service to high hardness values. Type WS is recommended for crusher jaws, impact hammers, pulverizers, etc.Type WSH is an austenitic nodular iron possessing superior tensile strength, toughness and ability to work harden under conditions of severe pounding impact. It is extremely difficult to machine. Recommended for crusher liners, hammers, grinding balls, etc.
