does titanium heat temper. when i used titanium i always doused it in motor oil. is that necessary i am going to buy 350 kilos of titanium sheet, and i want to know if i have to heat treat it.

WHAT ALLOY of Ti? Just like steel some alloys do and some do not! The CP grades do not.

What about AV series ?

it is grade 5

Grade 5 is Ti6Al4V and it can be heat treated. Does it need it well it depends on how you are getting it some is annealed some is hard.

So how is it heat treated?

Some alloys are "aged" by heating to 1500 or so and holding for many hours (up to 24!) in an oxygen and nitrogen free atmosphere. Doesn't have to be vacuum, inert gas is often used. Not something you want to try at home.

Whether you have to heat treat it depends on what kind of material properties you need. Are you making roses with spiffy anodized pink & blue colors? No heat treat needed. Are you making support thingies to hold up your heavy doo-dads? Heat treat might be needed there.

So... whatcha makin'?

He's makin' knives.

I make crowbars and tongs. Some big crowbars(5 feet long)

I have 2 pair of Ti Tongs, the first I made myself and the second I picked up for $10 at the last Quad-State---couldn't buy the material to make them at that price!
