Need source for Alloy 20 Metric fasteners in US

Need source for Alloy 20 Metric fasteners in US

(OP)
Current project involves hex nuts, hex cap screws and double end studs in Stainless but would like to have better yeild than A4 (316) can provide.

Does anyone have a good supplier for Alloy 20 (Carpenter Tech is the parent) or a similar readily available metric? Sizes are M20 and M24 on this part.

Also posting in Stainless Steel for Eng forum.

Thanks!

RE: Need source for Alloy 20 Metric fasteners in US

Alloy 20 is a thermocouple alloy and is not really suitable for fasteners. To obtain better yield than 316, next option up for me would be 321, a common alloy for fastener manufacturers, or A-286 depending on what yield strength you need. You will not find M20 and M24 bolts in these two alloys off the shelf, but can be made to order. Try :
www.alcoa.com/fastening_systems/
their european sites regularly use these alloys.
