Studies on the grindability of some alloy steels ...

18/08/2000  While the heat treated microalloyed steel and the low alloy steel are not likely to be work hardened too much during grinding at either ambient temperature or cryogenic temperature, the austenitic manganese steel work hardens rapidly under stress at ambient temperature and is likely to transform to martensite at cryo-temperature. The present study was designed to understand the

Manganese Steel - 6 Things You Need to Know AJ

Manganese Steel – 6 Things You Need to Know. 1. What is manganese steel? Manganese steel, also called Hadfield steel or mangalloy, is a steel alloy containing 12-14% manganese. Renowned for its high impact strength and resistance to abrasion in its hardened state, the steel is often described as the ultimate work hardening steel. 2.

Workhardening Behaviour and Microstructural Analysis of ...

Manganese steels are unequalled in their ability to harden, exceeding even the metal stable austenitic stainless steels. For example, standard grades of manganese steel containing 1.0 to 1.4% C and 10 to 14% Mn can work harden from initial of 220 Hv to a maximum of more than 900 Hv4-6. Indeed Hadfield steel is a remarkable engineering alloy
