PHILHARD Mn

AWS Specification : AWS EFEMn-B

JIS Specification: NONE

Other Specification: NONE

I. APPLICATIONS:

Rebuilding of HADFIELD steel rail ends, shovel, dredge buckets, heavy crushing equipment, like the jaw crusher, gyratory crusher cones, mantles, swing hammer, tooth crusher rolls, ore crusher crown wheels, and many more..

II. DESCRIPTION:

HADFIELD TYPE 14 % manganese for austenitic, non-magnetic weld metal suitable for joining and rebuilding components of the same type, subject to abrasion service with impact. Prior to weld thick rebuilding deposits over HADFIELD STEEL, it is necessary to “buffer” first the base metal with one of two layers of an austenitic stainless steel.

III. NOTES ON USAGE:

Avoid the continous welding and it is recommended to water cooling during welding.
It is necessary to underlay with austenitic stainless steel in such case when the base metal is not 13% manganese steel.
When the base metal of 13% manganese steel is hardened, remove it before welding.
Dry the electrodes at 150 - 200ºC for 30 – 60 minutes before use.

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

C	Si	Mn	Cr	Mo
0.60	0.17	14.20	0.53	0.53

V. HARDNESS OF WELD METAL:

Hardness, as welded, 3 layers weld metal 87-100 HRB (180 – 220 Hv)

work hardened 45 – 51 HRC (450 – 530 Hv)

VI. WELDING POSITIONS: FLAT, OVERHEAD, VERTICAL UP

TEST RESULT

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.
