Ms temperature

The temperature at which the transformation of austenite to martensite begins (starts).

Ms simply means martensite start. In low carbon, low alloy steels the Ms temperature is about 350ºC.

The Ms temperature varies, depending upon the carbon and alloy content of the steel, reducing as the carbon and alloy content increases.
