Low Mo content in ASTM 4140
Low Mo content in ASTM 4140
(OP)
What would be the consequence of a low Molybdenum content in ASTM 4140, say around 0.01-0.02%? I'm using the steel in the B7 condition in a tensile application.
Thanks for your help.

What, 0.01 to 0.02% in total mass of Mo in the steel or below the specified minimum of 0.15%? This is not 4140, if what you report is the mass percent of Mo. Check your numbers again.

As I thought. You better re-evaluate the use of this for stud material because low Mo is unacceptable. The B7 stud material is suited for moderate to elevated temperature service (up to 800 deg F), and if you have low Mo this would be unacceptable to me for service.
