What temperature does steel get brittle?

The ductile to brittle transition temperature is strongly dependant on the composition of the metal. Steel is the most commonly used metal that shows this behaviour. For some steels the transition temperature can be around 0°C, and in winter the temperature in some parts of the world can be below this.

In respect to this, does steel get brittle when cold?

Yes. Cooling just about anything to liquid nitrogen temperatures makes it more brittle than at higher temperatures. Metals become brittle at temperatures much warmer than liquid nitrogen temperatures. On a cold winter night in Iowa, the door on my brother's car was frozen shut.

Subsequently, question is, what happens to steel at low temperatures? The primary adverse effects that low temperatures cause are the loss of ductility (the ability to undergo plastic deformation before rupture) and increasing embrittlement of the material as the temperature falls below what is called the ductile-to-brittle transition temperature or DBTT.

at what temp does carbon steel become brittle?

A proper MDMT rating of -20 F for most carbon steels means that it will not enter this transition range until below -20 F. The material remains fully ductile until -20 F or lower temperatures are reached.

What temperature can steel withstand?

Scaling Resistance Most austenitic steels, with chromium contents of at least 18%, can be used at temperatures up to 870°C and Grades 309, 310 and 2111HTR (UNS S30815) even higher. Most martensitic and ferritic steels have lower resistance to oxidation and hence lower useful operating temperatures.
