Does anyone have experience of using austenitic stainless steel "254" as a corrosion-resistant alloy specifically in environments susceptible to chloride stress corrosion cracking and hydrochloric acid acid-corrosion.

 

Would like to hear some opinion on this from members familiar with this material.

 

Regards,

Ankur.

I wish I could give back to you at least a little bit of that much you give us all by sharing so kindly your extremely valuable knowledge, but I am sorry I cannot help you out on this one.

 

May our Lord bless you, best regards.

If you need the information for design the overhead crude tower, my recommendation is:

You need to know the amount of salts (ptb) in your system, the recommendation is less 2 ptb. If you have over this value, you need to work firstly about the crude desalting after this the metallurgical choice is more easy.

About the austenitic stainless steel “254” I have read in the web, this can replace titanium or hastelloy!!!, but I don´t work with this alloy in our Refinery (3000 bpd). I attached you information about “254”.

I hope the information will be useful for you.
