Wear Face Welding
DO 385 GMAW OAW is an iron based alloy with a near nanoscale (submicron) microstructure that includes chromium, molybdenum and niobium in the material chemistry, resulting in an overlay wear solution well suited for the toughest jobs in the most extreme service environments.
KEY PERFORMANCE CHARACTERISTICS:
– 66 – 71 HRc single and double pass weld deposits.
– Exceptional resistance to severe sliding abrasion.
– Provides longer lasting wear life than most chrome-carbide and complex carbide alloys.
– Improved impact resistance results from complex boro-carbide phases surrounded by ductile phases that form during welding.
Available in diameters : 1.2mm – 4.53Kg, 15Kg spools
1.6mm – 15Kg spool
Hardness after welding HRc: 66-71
ASTM G65-04 Procedure A 6000 cycles mass loss = 0.09–0.11g.
Weld deposit Density 7.36 g/cmᵌ
