Basic coated stick electrode for17 %
Cr- steels
Application field
UTP 660 is a basic coated stick electrode for joining and surfacing on martensitic, ferritic 17 % Cr-steels
of the same nature. Particularly for tight surfaces on gas, water and steam fittings.
Base materials
1.4510, 1.4057
Properties of the weld metal
The weld deposit of UTP 660 is stainlesss and corrosion resistant as similar 17%-Cr-steels, free of scale
in air and oxidizing combustion gas up to 950°C. Suited especially in sulphureous combustion gas in high
temperatures.

Welding instructions
Preheating, interpass temperature and postweld heat treatment must be adjusted to the prevailing base
metal and wall thickness. In joints and surfacings of similar ferritic Cr-steels, keep heat input very low because
ferritic 17%-Cr-steels tend to embrittlement by coarse-grained development. Re-drying 2 - 3 h at
250 – 300° C.
