Hi

Can you please tell me the temperature range for ASTM A439 Austenitic Ductile Iron type D2? particularly interested in the minimum?

RE: ASTM A439 Austenitic Ductile Iron type D2 Temperature range

Perhaps you can refer to the data provided by Ductile Iron Society.

http://www.ductile.org/didata/Section5/5intro.htm#Low Temperature Properties


"Properties and application of Ni Resist and Ductile Ni Resist alloys"  NiDI publication.

The later publication recommends use of D2 iron upto -196C (-321F) with no remarkable drop in impact properties. Please refer to the TableXX Low TemperatureImpact Properties of some Spheroidal Graphite NiResist Alloys.
