ARE ITS WORK-HARDENING ABILITY, TOUGHNESS, AND DUCTILITY THE ONLY ADVANTAGES OF MANGANAL?
No. It has a low coefficient of friction which is very important to wear resistance. This is particularly obvious in metal-to-metal applications. • HOW DOES IT BEHAVE UNDER IMPACT WITH NO ABRASION? One example of surface work-hardening under almost pure impact is the liners of shot-blast cabinets. Manganal work-hardens rapidly, takes a smooth polish due to its low friction property, yet retains its great toughness under the hardened surface. Generally, the heat-treated alloy and steels, although of high hardness, tend to erode comparatively fast, and break down on the surface. The use of high-manganese steel castings in certain railroad trackage is another example of impact with very little abrasion. • 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 su
