Submerged Arc Wires  

Postalloy 2933SA - Provides weld deposits that are similar in chemistry and heat-treatment to AISI 4130 steel.  Weld metal is machinable “as welded”.  Deposited hardness depends on welding procedure used.

Hardness:   as welded 32-36 Rc.

                       heat-treat up to 52 Rc.

Wire Type:    submerged arc

Recommended Flux:     neutral

Available Sizes: 3/32", 1/8" (2.4, 3.2 mm)

Postalloy 2940SA - Provides weld deposits that are similar in chemistry and heat-treatment to AISI 4140 steel.  Weld metal is machinable “as welded”.  Deposited hardness depends on welding procedure used.

Hardness:   as welded 38 - 40 Rc.

                       heat-treat up to 56 Rc.

  Wire Type:    submerged arc

Recommended Flux:     neutral

Available Sizes: 3/32", 1/8" (2.4, 3.2 mm)

Postalloy 2953SA is an iron base alloy that deposits weld metal similar in composition and heat-treatment to H-12 tool steel.  Weld deposits are hard and tough, resistant to abrasion, metal-to-metal wear and high compressive loading.  Retains hardness at elevated temperatures. Typical applications include work rolls, vertical edger rolls, flaking rolls, pipe forming rolls, leveler rolls, dredge ladder rolls, pins

Hardness:   50 - 54 Rc.

  Wire Type     submerged arc

Recommended Flux:    neutral

Available Sizes: 3/32", 1/8", 5/32”

                              (2.4, 3.2, 4.0 mm)

Postalloy 2930SA is a low alloy steel composition.  Use for build-up on carbon and low alloy steels.  Highly machinable.  The weld metal has good compressive strength, making it an excellent base for more wear resistant hard surfacing overlays.  Deposits are crack-free and with no limit on deposit thickness.  Typical Applications - Build-up underneath more wear resistant overlays.  Final overlay on journals, splines, threaded areas.

Hardness:   30 - 35 Rc.

  Wire Type:    submerged arc

Recommended Flux:    neutral

Available Sizes: 3/32", 1/8" (2.4, 3.2 mm)
