making the strongest and lightest stainless steel frame
making the strongest and lightest stainless steel frame
(OP)
I have been looking at some of the super duplex alloys and although I haven't ruled out doing Titanium, stainless would be easier to weld without difficult complications as the assembly becomes too large to avoid chamber welding.
Is 316B the logical and wisest choice for a tubular motorcycle frame whose tubing must tolerate cold bending and tig welding?
I do see some of the super duplex metals that have both high tensile and yield strengths but I'm not sure about their ultimate suitability..... especially regarding brittleness, cold bending, and welding.
All things being equal...... I'm not looking for it to be as light as a 4130 frame but would like a stainless frame lighter than 1020 or 1026......
Of course I'd like it to work good and last a long time under use. Thanks

I am reasonably sure that 316B is what the builders of stainless frames use but you very well may be right about the 316L
I was very impressed with the strength numbers of some of the exotic duplex metals but contacting the manufacturers so far hasn't answered all my questions since these metals are typically used for other applications.

Then again this is only really just a guess and I'm not even sure that the PH SS are available or suitable for this type of design.

I love materials science!
