In general, ethylene/ethane service equipment designed at atm, -104 degree C.
Hence,Stainless steel(SUS 304) is selected for such alow temp.service.CS is very very dangerous even low cobon content. See ethylene plant metalogy,if you can.

I would like to add more explanation on this subject.
System volume of slug ccatcher is about 4000 m3 and nitrogen source is limited. Hence I am looking for alternate method instead of high pressure leak test at 120 bars.
Now I am considering that just after finishing the hydrotest...
It's slug catcher,and TOTAL specification for leak test said that leak test should be done at the operation pressure.Is there any mechine or compressor to increase such a high pressure,120 bar.?
Or any alternative you have?
We are going to carry out leak test for slug catcher in gas seperation plant. However pressure requirement for leak test is max. operation preassure. Slug catcher is designed to operate at 80 barg to max.120 barg.
In addition media for leak test is designated with nitrogen. I think that this...
