Air Cooling 1144 Material ?

[mtnz]

Hi Guys!

I know 1144 is an oil quench material. I was just curious what happens if we air cool 1144?

Would it be still hardened ?

Thanks!

Thin parts? Forced air?
Might work.

1.5" thick, 14" long pin ?

 

[EdStainless]

No chance at 1.5" diameter in air.
Will it through harden even with an oil quench?

You mean it won't get hardened at all?

 

[EdStainless]

The outer surface will, but the properties through it will be lower, and maybe rather bad.
If this pin is going to be loaded you might want to re-think your grade.

I don't need to thru harden the pin. I need to case harden it, so I believe it will work then ?

Probably not; depends on the surface hardness and depth of hardness required.

I assume you still wish to air cool.

Are you buying 1144, or "sress proof" ?

 

1144 should respond very much like 1045, a very common material for which there is an abundance of data.

You can expect hardness around 269 HBW (28 HRC) after air cool in this section size.
