Re: [MW:20132] Stabilizing Heat Treatment of SS 321

We need to create titanium carbide to make steel capable to eliminate sensitizing at 450 to 780 deg range.

Subject: [MW:20112] Stabilizing Heat Treatment of SS 321

Dear Experts,

In one of our client project spec., it is specified that SS 321 pipes shall be in a stabilized HT condition. Stabilizing HT shall be carried out subsequent to the normal solution annealing. Soaking temp. & holding time for stabilizing HT shall be 900ยบ C & 4 hrs respectively.

My questions are (1) what is the purpose of stabilizing HT (2) This stabilized HT pipe shall be solution annealed after bending in coil form. Is it allowed or again we shall have to carry out stabilized HT after solution annealing? Client Spec. asks for solution annealing HT only after bending in coil form. 

Your prompt response on the above shall be highly appreciated.

Thanks & regards,


C. R. GANDHI
