Washers per ASME PCC-1, Appendix M
Washers per ASME PCC-1, Appendix M
(OP)
I just asked a well known bolt supplier about washers that meet the subject spec. It came as little surprise to me that he had never heard of it. Seems to be the story of my life. These are through thickness hardened washers for use in bolting up pipe flanges. Yes, I've seen all of the threads about whether or not you should use washers on pipe flanges. This will be for stainless steel flanges with stainless bolts. Let's just assume that I'm going to use them.
Does anyone know of a bolt supplier that will know what I'm talking about? Also, how would you call it out on a RFQ? I was hoping I could call out the size and say per ASME PCC-1-2013, Appendix M, Type 5. If anyone has experience ordering these bad boys I would love to get your input.

XL83NL, is the Hytorc you mention the one that sells the Hytorc Washer, the weird looking washer with a toothed edge? If so, I don't think they sale just plain 'ole flat washers.
One thing I noticed about PCC-1 is that it recommends a martensitic stainless steel washer for a austenitic stainless fastener (SA-193). Not sure I get this. Maybe you can make the martensitic steel harder. Just guessing, I'm not a metallurgist. Maybe I should start another thread for this question but does anyone know if that's OK to use for cryogenic applications?

Don't think SA-193 is suitable for cryogenic service.

Washers: The compatible washer for use with A320-L7 bolts is ASTM F436. Made from heat treated, hardened steel, F436 washers are capable of withstanding a broad range of environments including low temperature service.

Rconner, those are spring washers. I was looking for plain flat washers. I don't know, maybe I should consider them.

Isn't it kinda the same as with buying an A312 TP316 pipe for use under B31.3? The pipe itself doesnt comply with B31.3, but can be used under B31.3.
