Cryomate-3:

Nickel-base alloy electrode, with lime-fluride coating for yielding weld deposit which combines properties required for a wide range of applications in terms of base materials and service temperature in the range 900°C to -250°C Mn & Nb additions confer high degree of resistance to hot cracking

Identification:Name Printed

Application:

Ideally suited for welding of nickel-base alloy, such as Inconel 600, Nimonic 75, Monel 400, to themselves or to mild steel, low alloy steels and Stainless steels.
In many cases of dissimilar joints, need for preheat may be eliminated.
Transition welds between creep-resisting steel such as ferritic 2Cr-1 Mo, and austenitic steels such as 316H, for elevated temperature service in petrochemical and power generation plants.
Low temperature applications such as 5% Ni & 9 Ni steels used for cryogenic vessels and pipe work, in service temperature below-100°C.

Notes on usage:

Thorough cleaning of joint faces is imperative to prevent pores.
Use short arc to the extent possible.
Ensure minimum amperage consistent with proper fusion so as to control heat input.
Stringer beads are to be preferred, but weaving.When necessary, be restricted to less than 2½ times of the core wire diameter.
Redry electrodes for two hours at 250°C-300°C Transfer them to holding oven maintained at 80°C-100°C.
In order to avoid crater crack, fill up crater properly and draw the arc away to the side.
Preheating & Interpass temperature and PWHT may be employed as necessary for base materials.
