Postalloy Forging Die Repair and Flood Welding Wires

These alloys are designed with a very efficient deep penetrating flux/slag system that pulls contaminants out of the molten weld metal and absorbs them into the slag.  The resulting weld metal has a very low level of interstitial contaminants and ultra low level of macro contaminants.  Weld metal deposited with these alloys provides very consistent mechanical properties that yield consistent, reproducible results.

Hot-Working Tool Steel Alloy Wires   

Postalloy 2742-FCG – An iron base low-carbon chrome/moly/tungsten hot-work tool steel used when machinability in the "as-welded" condition is required - very good thermal fatigue resistance. Excellent resistance to heat-checking when subjected to water quenching.   Uses include the repair of spalled or heat-checked areas on hydraulic press and drop hammer forging dies; filling in complete impressions that are to be recut to dimensions; worn areas on rams and sow blocks.

Hardness:    38-43 Rc

  Wire type:     flux-cored, gas-shielded

Available Sizes: .045", 1/16", 3/32", 1/8"

                              (1.2, 1.6, 2.4, 3.2 mm)

Postalloy 2747-FCG – A tough iron base chrome/nickel/moly hot-work tool steel alloy.  Alloy chemistry is balanced to provide weld metal with maximum wear resistance while still being machinable.  Deposits reach maximum hardness as deposited and can be tempered to a lower hardness if desired.  Weld deposits are shock-resistant, and are highly resistant to heat-checking, oxidation and wear.  Excellent choice for repair of deformed, broken, spalled or heat checked areas of hydraulic press and drop hammer forging dies.  For filling medium deep impressions that are to be re-cut to dimensions.

Hardness:    44-49 Rc as-welded

                       38-42 Rc as tempered

  Wire type:     flux-cored, gas-shielded
