Designed for use on carbon and low-alloy steels, manganese steels and cast iron. Deposits take a high polish, which contributes to high frictional and abrasion wear qualities, especially small particle abrasion. Excellent on applications that need impact as well as abrasion resistance. Perfect Pass 9009 provides optimum resistance to this combination and deposits well out of position. This alloy also has good hot hardness up to 1,000° F. Perfect Pass 9009 is especially designed for crusher applications and is used heavily in construction, mining, brick and clay industries on parts such as crusher rolls, jaw crushers, bucket teeth, edges, hammers, mill hammers, conveyor screws and more.
