Common Failures of Hadfield Steel in Application

austenitic manganese steel. The freezing range of Hadfield steel is 1371 o C to 1250 o C. High pouring temperatures may create large superheats, which according to Balogan [8] should not exceed 120 o C. With high temperature regimes, castings cool slowly because metal stays hot for longer. This however depends on the size of casting.

Casting - Modern Eq

Die Casting Description: Molten metal is injected, under pressure, into hardened steel dies, often water cooled. Dies are opened, and castings are ejected. Metals: Aluminum, Zinc, Magnesium, and limited Brass. Size Range: Not normally over 2 feet square. Some foundries capable of larger sizes. Tolerances: Al and Mg ±.002″/in. Zinc ±.0015″/in.
