Timber, iron or steel.

We found a section of the Whydah hull under 20 feet of sand from 1717

timber, old Spanish ship.

It depends on oxygen.... the less there is ... the more you will have preserved.

There of lot of factors to consider water depth water temperature. exposure to sunlight and oxygen. The marine environment is very corrosive met destructive and marine parasites depending oxygen levels and with different timbers. Teak seems the most har wearing.

When I sailed around the pacific we had a joke that we was sailing on liquid sandpaper.

Oxygen.... is the main and pretty much the only major factor.
zero oxygen.... nil to zero decay.

PS>.. The "dead zone".... is Zero oxygen.

Depth and salinity also can play a part in situations of low oxygen as well like you stated.
But overall...
No oxygen.... no change.
Like space.
Still.
Dead.
Decay is an oxygenated lifeform(s)... so void of oxygen... no oxygenated life = very nil to little... to no decay.

And apparently depends quite a bit on the temperature of the sea. Don't know the construction material though.

Well heat is THE accelerator of everything - all life.
Cold the decelerator.
In this equation / question / theory on / of decay...
Temperatures only factor in if oxygen is present.

Temperature only accelerates or decelerates decay AFTER oxygen is present...
So.... still... No oxygen... still no matter... No life.
No life... No decay.
Hot or cold.

Now... with that said... enough heat... in the right enviro... and oxygen can be created.
And enough heat... breakdown will still occur...
But that type of heat is not happening in the scope of this.

Cool, Ill tell you the scenario .
My friend found 2 ships, both is sand with just a part sticking out, i suspect over 400 years old.
one is In the high tide where the ocean is about 54 degrees.
the other is in the estuary of a river, submerged under fresh water 90 percent of the time and diluted the rest.
In 1920 he figured they where buried in the sand on purpose other wise they would have been destroyed.
Oddly enough he showed me these chunks of silver his dad found.
He said he hacked them from a wall in a old mine around 1910.
