Front sway bar and springs

[Sauron327]

Sway bars on cars I restore were natural steel. Don't want to maintain it? Simple. Go in your paint booth and mix a that will match, I do it everyday. Gotta love a person who will dump 400k into a car only worth 100K at best.

I've yet to see a Legends Manual so not for me to shade it. But if everyone is supposed to dissect pertinent info out of pics that normally would show what or how to achieve successful restoration procedures, I can understand the confusion.

My opinion is that the manual is very good and I have learned some things I didn’t know.
I’m glad I purchased it.

Springs were heat treated, sent to the plant and installed. There was no coating on them.  It's a hard steel and doesn't rust like softer steels.
They may have been dipped in an oil as part of the heat treat - exceeding my knowledge here.

Oil quench after heat treating.

Depends on the steel if they need to use an oil quench. Without knowing the steel.....

Thank for the knowledge, thanks Jim for pointing out the end links, I will now change to correct ones.

my goal is to restore this car to look like a brand new factory unrestored show room new car. (Not over restored). Original dated sheet metal everywhere, ALL nuts and bolts factory correct originals, all components assembly line correct and dated as build date on trim tag, factory painted as the factory would have, only exception being base coat clear coat paint.

Are the sway bars not carbon steel?  If they are then they were oil quenched.  If an alloy then oil is not required to quench.

I have seen painted coil springs.

All steels are an alloy and carbon steel isn't very specific. You can quench is all kinds of mediums which cause different heat transfer rates. Water quench is commonly used for lots of steel grades. Oil has a slower cooling rate.
I'll nudge Rich and he can expound on the topic at length.

My once per decade login/post.     What Kurt said is correct, in that there are all sorts of heat treats and all sorts of alloys, even just within the generic class of carbon steels.  Without knowing the details of the metallurgy (and I'm not privy to the alloys being used for roll bars at that time, or any time for that matter) or the specific design objective, the part could be air quenched, water quenched, oil quenched, (some other medium), or no heat treat at all (though that is less likely than some type of quench).  Rich

Thanks for the replies,
I’m aware of quenching processes.  The premise of my original statement was Kurt mentioning oil after heat treat.  Hence me saying oil quench.  Fair point on all steels are alloy.  My point was if using an alloy like chromoly or A-2 or even D-2 then it would be oil quench.

Here is an interesting read along with videos on how Hellwig makes their sway bars..  btw they are oil quenched.

And yes I’m aware that D2 & A2 are tool steels.  “I’ve been doing this for 10 years..”. Sorry I couldn’t resist..
