Austenitic steel resistant to wear combined with shock - contains high percentage of manganese, plus carbon, chromium and titanium (DK 2.4.79)

摘要

The steel contains 16-23% manganese, 1.1-1.5% carbon, 0-4% chromium, and 0.1-0.5% titanium, the remainder being iron and the usual trace impurities obtd. during melting. As compared with the conventional Hadfield's manganese steel, contg. 12% Mn, the new steel has superior resistance to abrasion and shock.
