Can anyone provide the minimum temperature limit allowable for AISI 4142? I need data showing -143 F is acceptable. If you have any supporting document would be helpful?
 
What is the chemical composition of your material (especially sulfur and phosphorus)?

What is the heat treatment and microstructure?

What are the loading conditions?

Regards,

Cory

More important, acceptable? This is a relative term, and must be quantified by a minimum CVN value specified at -143 deg F. Is it 10 ft-lbs, 25, 40 70...... at -143 deg F????
