White Irons are generally specified for applications requiring a hardness range of 200 / 300 HBN, High Chrome Alloys (typically 28% Cr addition) are specified for applications requiring HBN figures of 600 – 650 HBN and Ni Hard castings are supplied in a range of grades that offer a hardness range of between 500 – 600 HBN.

With post casting heat treatments the hardness range of high chrome alloys can be extended to 700HBN.

All of the wear resistant materials available have alloy additions to varying degrees, chrome is the main element but copper, molybdenum and vanadium can be introduced to the base Grey Iron Material.

All of the Wear Resistant Cast materials present challenges when it comes to machining careful use of steel inserts and ceramic tooling and know how allows us to undertake the supply of fully machined castings. We product deferent kind and size of Hammer crusher.
