Alloy 617 Applications
Alloy 617 B is specifically designed for use as a pipe and fitting material for steam generators in power plants
with supercritical steam parameters (700 °C power plants).
Alloy 617 B is a nickel-chromium-cobalt-molybdenum alloy with excellent strength and creep properties. It was
developed on the basis of Alloy 617, to meet the high demands of power plant technology for 700 °C power plants.

Alloy 617 Mechanical Properties
Welding Alloy 617
When welding nickel-base alloys and special stainless steels, the following instructions should be adhered to:
A separately-located workplace, which is specifically separated from areas in which carbon steels are being processed,
should be used. Maximum cleanliness is required, and draughts should be avoided during inert gas welding.
Tools used for other materials must not be used for nickel-base alloys and stainless steels. Brushes should be made of
stainless materials. Processing and machining equipment such as shears, punches or rollers must be fitted with means
(felt, cardboard, films) in order to avoid material contamination with ferrous particles, which can be pressed into the
surface of the material and thus lead to corrosion.
