[MW:25828] Re: For Cryogenic Services at Temp -196 degree Celsius (17 Kelvin) Pipe of ASTM 312 TP 304 L is suitable?

Dear experts,

For Cryogenic applications which involves Minor Welding, I would suggest to use SS304LN, SS316LN. I would say there no economical replacement for these grades with same properties.

They have excellent impact toughness values even at -196 degrees they would show more than 80J value.

But due care has to be taken during welding since these grades are susceptible for liquation cracking.

Thanks

Dear Experts,

Currently I am working on a project of ISRO (Indian Space Research Organisation) for Integrated Cryogenic Engine Testing Facility (ICET), for bidding in that services are Liquid Hydrogen, Liquid Oxygen, Liquid Helium, Liquid Nitrogen, Gaseous Hydrogen, Gaseous Oxygen, Gaseous Nitrogen, Gaseous Helium.
For SS Seamless Pipes client has given three options for material ASTM 312 TP 304L/ ASTM 312TP 316L/ ASTM 312TP 321.
Kindly suggest me the suitable material for the same that gives economical and best design.

Thanks in advance.
