WHAT IS UNUSUAL ABOUT IT?
Manganal thrives on severe wear conditions. The more impact and hammering it receives, the harder the surface becomes. This characteristic, known as work-hardening, plus the fact that it remains ductile underneath, makes it a most effective steel in combating impact and abrasion. • HOW AND WHEN DID HIGH MANGANESE STEEL COME INTO BEING? It was discovered by Robert A. Hadfield in Sheffield, England in 1882, and was first produced in the U.S. in 1892. • WHY IS IT WIDELY USED? It has very high strength, ductility, toughness, and excellent wear resistance in the most punishing applications. • IN WHAT FORMS IS IT AVAILABLE TODAY? It is available under the trade name Manganal as plates, hot-rolled bars and special shapes. • WHY IS MANGANAL DIFFERENT FROM CASE-HARDENED STEELS? With carburized or case-hardened steel, the depth of hardness is fixed. When Manganal is subjected to wear the hard surface continuously renews itself. • HOW HARD CAN THE SURFACE GET BY WORK-HARDENING? Depending on defor
