PHILSTAIN 303

AWS Specification: AWS A5.4 E312-16

JIS Specification: NONE

Other Specification: NONE

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 303 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.
