Cast iron and heat

Cast iron and heat

(OP)
At what temperature will cast iron distort?

RE: Cast iron and heat

All of them.

RE: Cast iron and heat

700 °C

RE: Cast iron and heat

(OP)
How detrimental is 700 deg F to grey cast iron, will it stress relieve enough to need remachining? I know remachining is needed if its into the 1400 deg F range. Sorry I ran out of time and just couldn't finish the first post.

RE: Cast iron and heat

What grade of cast iron?

What is the starting state of the piece? As-cast, machined, already tempered or annealed?

Heated how?

Cooled how and for how long?

The possibility for distortion is largely dependent on geometry.

RE: Cast iron and heat

(OP)
Just typical engine blocks heads etc.
