NEXA 312-16 ELECTRODE FOR HIGH STRENGTH STAINLESS STEEL
For Dissimilar Joining
CLASSIFICATION
AWS A/SFA 5.4 E-312-16
DESCRIPTION
Nexa 312-16 is a rutile type stainless steel electrode, specially designed for welding similar and dissimilar steels. Electrode produces crack free high strength joint in carbon steel, low alloy steel, stainless steel including difficult to weld steels.
APPLICATIONS
* Dissimilar joints between stainless steel & high carbon steels and unknown steel.
* Welding difficult to weld steels ex, high c hardenable tool, die and spring steels,13 Mn steels,free cutting steels,high temperature steels,cast steels
* Suitable for problematic steels with higher strength such as pressing dies, trimming tools, armor plates.
