[Bird 426]

Cheap grade stainless rusts just like regular steel.

Nobody asked which is the best but why don't you tell us and give a detailed explanation as to why one is better than another for a simple anti collapse spring. Specifically, post results of your research with structured sections like an introduction, literature review, methodology, results, and conclusion. Waiting........

I could speak of the various attributes of each particular alloy, in terms of its metallurgy, and physical properties but it sounds as if it's out of your understanding and comprehension........., and YES stainless steel will "rust" due to chloride corrosion........

You're the expert so please do speak on the various attributes, properties, and mettalurgy of austenitic, ferritic, martensitic, duplex, and precipitation hardened stainless steels and which is "best" for anti-collapse springs in an automotive coolant environment. Don't do it for me but for others who can comprehend such complex subjects. Remember, we want to know which is "best" and why.

A few years ago my buddy called me over because he had trouble with cooling his 383 69 Roadrunner. The lower hose was fully collapsing. He looked at me and said now what? He followed me home, I stuck some SS spring wire around broom handle while slowly turning in a lathe and walla - perfect spring for the hose!

But for full disclosure, my dad taught me how to make springs long ago. I have all his spring tooling.
