Low Temperature Ratings for Metals

Low Temperature Ratings for Metals

Low Temperature Ratings for Metals

(OP)
I'm looking for reference information regarding low temperature ratings for metals specifically 304,316,321, and 347 stainless steels.

RE: Low Temperature Ratings for Metals

In the case of API-650 tank construction, 304 and 316 may be used at any ambient temperature.  For pressure vessels, I think ASME VIII states that 304 and 316 may be used down to about -240F.  API-620 permits the use of SS for cryogenic temperatures, such as for LNG tanks.

RE: Low Temperature Ratings for Metals

ASME BPV code gives temperature ratings for those materials.  I can't remember for sure, but I don't think you need any kind of impact testing down to at least -320, possibly lower.  

RE: Low Temperature Ratings for Metals

Please find the following limitation in ASME.

Temperature Limitation (deg.F) of Materials in ASME Code, up to add. 2004

Materials        Sec VIII-1        Sec VIII-2        B 31.3

304 SS            -320~1500    -320~800    -425~1500    
316 SS            -320~1500    -320~800    -425~ 800

321 SS            -320~1500    -320~800    -325~1500    
347 SS            -320~1500    -320~800    -425~1500
