DESCRIPTION
Azucar Ss31o is a all position rutile basic coated electrode of the 25M chromium and 20% nickel type. It is good for welding heat resistant AlSl310 grade materials and resists scaling in oxidizing atmospheres at temperatures up to 1100″ C while maintaining adequate joint strength.
MECHANICAL PROPERTIES
Tensile Strength (Mpa) => 580 (=58 kg/mm). Elongation on 4D :> 37%
APPLICATION
This is good in welding 25/20 stainless steel and welding of unknown steel to stainless steel. This is good for high temperature applications like heat exchangers, heat treatment trays and boxes, vats, tanks etc. This has low spatter loss with high strength and elongation properties.
TECHNIQUE
Before application the surface needs to be cleaned of fatigued deposits oil grease etc. The joints needs to be prepared.
RECOMMENDED AMPERAGE
4.00mm X 350mm – 120 to 140Amps.
Polarity DC + AC 70 OCV min.
