PHILHARD 4140

AWS SPECIFICATION: NONE

JIS sPECIFICATION: NONE

Other Specification: NONE

I. APPLICATIONS:

PHILHARD 4140 for welding and hardfacing of parts made from ASTM 4140 steels. In addition to its use for welding rolled plate steel, foundries are a principal user for repair welding high-tensile castings.

II. DESCRIPTION:

PHILHARD 4140 is an all-position, low hydrogen electrode designed for welding SAE 4140 and similar heat treatable steel where the weld metal must match the heat treating properties of the parent metal.

III. NOTES ON USAGE:

PREHEAT:

When heat treatable steels are welded with any ferritic electrode, including PHILHARD 4140, it is necessary that the weldments be preheated to 400-600ºF (204-316ºC), with the same temperature held at interpass, in order to prevent cracking.

IV. TYPICAL CHEMICAL COMPOSITION OF WELD METAL (%):

C	Mn	Si	P	S	Cr	Mo
0.35	0.86	0.4	0.012	0.014	0.85	0.35

V. HARDNESS OF WELD METAL: (as welded without oil quenched) 27-30 HRC

VI. WELDING POSITIONS: FLAT, OVERHEAD, VERTICAL

The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. 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.
