PHILSTAIN 307

AWS Specification: AWS A5.4 E307-16

JIS Specification: Z 3221 D307-16

Other Specification: DIN 8556 E188 Mn R 36 140

 

I. APPLICATIONS:

Welding of 14% Mn steel, steel armour, hardenable steel and generally all hard-to-weld steels. Joining of wear plates to each other and to their supports. Joining of stainless steels to carbon steels. Building up of rails and buttering layers before hardfacing on 14%Mn steel or on steels of unknown composition or on carbon steels. Extensively used in steelmaking public works, mining carrying and dredging.

II. DESCRIPTION:

PHILSTAIN 307 is a lime-titania stainless steel electrode which may form the deposited metal of 19%-9%Ni-5%Mn stainless steel with the perfect structure of austenite. The deposited metal has excellent crack resistibility and has easy work hardening.

III. NOTES ON USAGE:

  • Remove dirts such as oil and dust from the groove.

  • Normally, preheat is not necessary.

  • Keep the welding current as low as possible.

  • Keep the arc length as short as possible.

  • Rebake the electrode at 200-250ºC for about one hour before use.

Typical data and Test results for mechanical properties, deposit or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
