Metallurgical Options
In general, jaw plates are made of high manganese steel, which is considered the dominant wear material. High manganese steel is also known as Hadfield manganese steel, a steel whose manganese content is very high and which possesses austenitic properties. Such plates are not only extremely tough but are also quite ductile and work-harden with use.
We offer jaw plates in 13%, 18%, and 22% grades of manganese, with chromium ranging from 2% to 3%. Alloying elements can be added upon requirements, such as Mo (molybdenum) or wear-resistant inserts.
We keep a chemistry inspection report for each order, even each jaw plate, for quality tracking purposes.
