Moving Laser Heating


I am Trying to simulate a Laser heating of block of steel, the laser moves in a 80 mm straight path. my Problem is, the Temperature is almost steady along the path , for example 200°C [+5,-5], but in Reality the Temperature must increase along the path. for example at the beginning 200°C and after 80 mm 350°C or higher.
I chose the matrial form Library ( Structural steel).

Do somebody have an Idea, what is wrong?
