Name : WB36 (T36/P36, 15NiCuMoNb5-6-4) HOT ROLLED TUBES FOR HIGH TEMPERATURE AND PRESSURE APPLICATIONS
Definition :
WB36 is a bainitic Ni-Cu-Mo steel micro-alloyed with niobium. It is also known as 15NiCuMoNb5-6-4 according to EN 10216-2 and VdTÜV377/2, T36 according to ASTM A 213 and P36 according to ASTM A 335.
Challenges :
WB36 exhibits excellent high-strength properties up to 450 °C. The reduced weight of the feedwater piping components compared with conventional carbon steel allows improved resistance to thermal fatigue and very good heat transfer.
