Abrasion Resistant Plate and Manganese Steel Plate are both types of steel products that have been specially made to endure extremely hardwear, tough impact, and mechanical stress in harsh operating situations. Such materials find their use on the very broad basis of mainly those industrial sectors where the parts are under the action of constant friction, sliding contact, or the effect of heavy impact loads.
Abrasion resistant (AR) plates refer to steels that are alloyed with high-carbon content and whose hardness has been specially improved, which hardness is usually determined according to the Brinell Hardness (HB). The most typical grades are those which have been manufactured according to the standards of ASTM International, such as the ASTM A514 and ASTM A517. Their precisely controlled chemical composition, as well as their heat treatment processes, give the plate a hard surface while a certain toughness is kept. This combination works in such a way that the material loss resulting from the rubbing of the surface is minimized in those cases where the plate is used in dump truck bodies, hoppers, chutes, crushers, and conveyor systems in mining and construction industries.
Manganese steel plate, which is mostly thought of as being ASTM A128 in terms of ASTM International standards, comprises a very high amount of manganese that usually reaches 11-14%. Because the steel was given this unusual composition, it is capable of work hardening through impact. Each time it is hit or pressed, its surface becomes very hard while the inside part still remains ductile. This feature makes it perfectly fit for the use of such heavy-duty items as crusher liners, railway crossings, dredging equipment, and impact areas in power plants and marine operations.
Essentially, abrasion resistant and manganese steel plates are of such an industrial importance that they allow one to maintain the structure and the efficiency of the equipment or installations in the highly erosive industrial conditions.
