Nil-Ductility Transition Temperature

[12mmc32]

Dear Sir,
I want the nil ductility transition temperature range for the different material... also specially for steel, Cast Iron and Nodular Iron.

Search for it on the internet, not on a forum.

Dear i am searching on internet but not getting value....internet not showing results properly

Carbon and low alloy steels have a huge range of nil-ductility temperatures depending on chemistry, melting, thermomechanical processing and heat treatment. Your question denotes a total lack of understanding of material toughness properties.
As an example of the nil ductility temp in API 5LX52 that we ran over 35 years ago, the nil ductility temp ranged from near 0 F to over 125 F.

What ductility do you expect in cast iron,that you are searching on the net.A visit to a good library will yield the results you desire.
