There is a difference between britteness and strength so be careful.
When a material is brittle it has a very short plastic stage (how much more force it can resist after the limit of proportionality) and a strong material is one which can resit a great tensional force before breaking. For example you could have a metal that can withstand an elephant to walk on it(strength) but as it reaches a certain point it snaps (brittle) and you can have a metal clip that will break after you bend it too much (strength) but has a long plastic stage as it can extend more and stretches more after the proportional limit.

Back to your question steel is made brittle or not depending on what it is used for the more carbon that is put in it in a molten form the mor brittle it becomes.

Brittle Steel

Stainless steel is not generally brittle and nor does it become brittle when cooled (bottom of class whoever said that - zero points). Stainless steel is a body centred cubic crystal, and only face centred cubic crystals are prone to becoming brittle when cooled.

The reason it is not brittle is that dislocation can run freely through its lattice. If you introduce a lot of impurities to the lattice, the dislocations become blocked. This makes the material stronger, but more brittle (it fails by fracture rather than by deformation, but at a higher stress).

Steel is an alloy so contains a mix of other elements. Stainless steel contains a lot of Chromium, which is malleable making it less brittle than normal steel, which has more brittle iron in it.

Depends to a certain extent on which stainless steel you are using, but no, it contains a higher percentage of chromium, which prevents corrosion, unless you are using an austenitic stainless steel which has magnetic properties.

We tend not to say brittle, but "short" (as in shortbread), brass is typically either "hot short" or "cold short" ie it breaks off in small pieces depending on temperature when you machine it, unlike steel which produces long pieces of swarf when machined.

So no, generally most stainless steels are not "brittle"

stainless steels design not to be brittle in their working conditions.but if you put lots of stress on them and in lower temprature they may brittle.

It's not brittle in normal temperture....
