Product Description

STELLOY 12-G X 2.0mm

Welding products and techniques evolve constantly. All descriptions, illustrations and properties given in this data sheet are subject to

change without notice and can only be considered as suitable for general guidance. This document is intended to help the user make

the correct choice of product. It is his responsibility to assess its suitability for his intended application.

CLASSIFICATION

EN 14700: T Co2

ASME IIC SFA 5.21 / AWS A 5.21: ERCCoCr-B

Cobalt base tubular wire for gas shielded metal arc hardsurfacing

Exceptional resistance to metal-to-metal wear in corrosive media at high temperatures, to erosion and to

thermal shocks

APPLICATIONS

Stelloy 12-G is used for hardsurfacing parts undergoing the single or combined effects of metal-to-metal

wear, abrasion, temperatures ranging from RT to 800°C and corrosive environments.

Examples

Saw teeth, cams, shafts, tappets and push rods for engines, screw conveyors and augers for rubber and

plastics, seats and valves for oil and gas…

TYPICAL ALL-WELD METAL MECHANICAL PROPERTIES

Hardness:

Three layer deposit on mild steel: 46 HRc

High temperature hardness:

20°C           200°C        400°C       6 0 0 ° C   800°C

450 HB     420 HB      380 HB     360 HB      230 HB

Higher hardness (up to 50 HRc) is possible in the first layer when dilution is minimised ( Ø 1.2 mm wire

welded at approximately 16 V).

High deposition rates and low dilution are facilitated by pulsed current

High heat inputs favour lower hardness
