WB36-15NiCuMoNb5-pipe  Alloy Steel Pipe

WB36 is a bainitic Ni-Cu-Mo steel micro-alloyed with niobium according German standards DIN WB36 . It is also known as 15NiCuMoNb5-6-4 according to EN 10216-2,ASTM A213 T36 and ASTM A335 P36.

WB36 seamless steel pipe (or 15NiCuMoNb5) was first developed by the German Mannesmann Company.Because of it’s high strength characteristic, WB36 pipe can be used for high pressure pipeline of temperature up to 500 ℃, or high thermal power unit parameters, such as supercritical unit of boiler steam drum, steam separator, header, steam generator, steam pipe, and high temperature or high pressure waterwoks of nuclear power equipment.

15NiCuMoNb5 pipe chemical composition and Mechanical property are shown as figure below:

The greatest advantages of WB36 alloy pipe is 100% recovery, environmental protection, energy saving, resource saving. The Chinese government encourages to expand the application field of wb36 high-pressure alloy pipe.

At present,The China’s consumption of wb36 pipe for the proportion of total alloy steel pipe only half as much as that of the developed countries. WB36 alloy pipe using field provide a broader space for the development of industry.According to the research of the Chinese special steel association WB36 alloy tube branch, the future of our country high pressure wb36 alloy tube material demand grew by an average of up to 10-12%.
