Need source for Alloy 20 Metric fasteners in US

[sprintcar]

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!

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 :

their european sites regularly use these alloys.
