@Ashok.

But please tell me Why one wants to make Steel BRITTLE, rather it should be somewhat Ductile to show yielding behaviour? Please explain.

Only carbon content is responsible for Ductility or brittleness of a material!

Phosphorus has no influence on mechanical properties.

Phosphorus additions can be used to strengthen sintered iron. But at contents above 0.6% P, the alloy becomes brittle.

What is brittleness of "cold"?

And I think that's coal.

What is the exact answer? Please tell.

Kiccha said:   7 years ago
Carbon causes the Brittleness then why answer is phosphorous? Anyone explain the exact answer.

But carbon content is the cause of brittleness and ductility. So why it is phosphorus?

Brittleness of which material?

Maybe something missing in this question. Am I right?

Jagdish said:   8 years ago
Sulphur is the right answer.

And red brittleness is due to an excess of phosphorus.

Srkhan toor said:   6 years ago
Phosphorus increases hardness and brittleness, so given answer is correct guys.

Should be the right question Brittleness of cold steel is due to an excess of.
