Product Description :

For welding 26%Cr Ferritic Stainless Steels.

A special rutile based flux with a positive ratio of chemically basic minerals to acid minerals that contains all the major alloying elements which is extruded onto a high purity ferritic wire. The use of balanced silicates ensures both strength of coating and resistance to moisture absorption.

Welding Features Of The Electrode :

The arc stability is excellent on both AC and DC+ as is the electrodes ability for initial arc strike and re-striking. Spatter is minimal and the slag is readily detachable leaving smooth evenly rippled seams of pleasing appearance. Metal recovery is some 130% with respect to weight of the core wire. 

Applications And Materials To Be Welded :

  • For welding 26% chrome ferritic steel when excellent resistance to stress

  • corrosion cracking in oxidising acids or in severe sulphidising condition needed

  • which often found in production plant in the copper industry.

Typical material includes :

  •  442 steels – ASTM A 176

  •  446 steels – ASTM A 276

  • This electrode suitable to used in condition which is unable to post weld heat treat. In all case, pre-heat temperature should be 150 to 200 C, and interpass temperature must be as close to pre-heat temperature, and closed by one of two PWHT.
