HOW DOES IT WORK WITH NO IMPACT BUT WITH COMPRESSIVE ABRASION?
Here again it surface work-hardens, takes a mirror-like finish, and retains its original underneath toughness. An example is wear strips under conveyor chains. The compressive abrasion of metal-to-metal contact deforms the surface structure of manganal and therefore, work-hardens it rapidly. The polish that it develops and its low coefficient of friction not only reduces the wear on the conveyor chain, but usually results in reduced power requirements for operating the equipment, because of reduced friction. • HOW ABOUT MANGANAL STEEL USED WHERE THERE IS BOTH IMPACT AND COMPRESSION ABRASION? The same qualities mentioned in 9 and 10 are developed. An example is quarry rock crushers. The high impact and grinding abrasion destroys most other steels rapidly. Manganal withstands the punishing abuse, without breaking or quickly eroding. Other typical uses are shovel buckets, teeth and loaders working in earth and stone where there is a general mixture of impact/compressive abrasion. • HOW DO
