The correct answer is 600° C.

The recrystallization temperature of steel is typically around 600° C (1112° F). This is the temperature at which the steel's microstructure changes, and new grains form, replacing the deformed grains created during cold working. Recrystallization occurs when the steel is heated to this temperature, allowing the material to regain its original properties, such as ductility and toughness.

The other options are incorrect because:

- 400° C (752° F) is too low for recrystallization to occur in steel.
- 800° C (1472° F) is above the recrystallization temperature and is closer to the austenitizing temperature, where the steel transforms into austenite.

So, The exact recrystallization temperature may vary depending on the specific steel alloy and its composition.

No 723 degree + 50 - 70 * C is answer. Not exactly 800*C.

723° is the correct answer.

It varies from 400 to 700.

It's 723° C.

Right @Pralay.

It is 1000 degree Fahrenheit

The correct form is in 723° c.

The recrystallization temperature for steel lies between 400 and 700 degree centigrade.
