Fastener High Temperature Service Limit

[koneill44]

Does anyone know where I can find a convenient chart that lists all the different fastener grades and their associated high temperature service limits?

Something like this

but with high temperature service limit as well.

koneill44, one source: ASME Sec II, Part D, Table 3. Free online for members, otherwise not.

Various piping specs or other PV Codes may have them as well.

Regards,

Call the mfg!!!

koneill44, you can contact the Fastenal engineering group using their contact e-mail from their website. They have a general service temperature guide for a number of different grades of fasteners.

koneill44,

one note of caution from experience - be aware that the ASME code temperature limits were based on 'design' bolt loads, typically 25% of yield strength. As such, in operational duty, the temp limits are curtailed by the normal bolt loads of approximately 50% of Ys.

Just my two cents.

Here's a convenient common one... this is mostly concerning the ASTM/ASME grades that are common in the process piping & heavy industry worlds... not really the grade 5 / grade 8/ SAE type stuff... it has some of the common alloys & a few uncommon ones as well.

click on fasteners, and then fastener data

Helpful for a quick reference...
