I am surprised at the high levels of retained austenite detected. The only solution is to heat trea the casting by heating to 800Celsius and holding for a minimum period of 4 hours depending on the section thickness and then air coling. If you desire I could take up the manufacture of this Nihard casting on a trial basis.
