PHILSTAIN 312
AWS Specification: AWS A5.4 E312-16
JIS Specification: NONE
Other Specification: DIN 8556 E29 9 R 26
I. APPLICATIONS:
Welding of dissimilar metals such as stainless steel to mild steel and low alloy steel.
Welding of stainless clad steel. Under-laying of hard surfacing.
II. DESCRIPTION:
PHILSTAIN 312 is a lime-titania type electrode which gives 29%Cr-9%Ni. As the weld metal has high ferrite structure, its crack resistibility is excellent. It is used for welding of dissimilar metals and underlaying welding of hard surfacing.
III. NOTES ON USAGE:
-
Choose the welding current as low as possible to prevent cracking of plate.
-
It is necessary to preheat the plate at 200ºC and over in the case of welding of special steel such as high alloy tool steels.
