  英国WA STELLOY 12-G、ERCCoCr-B钴基堆焊焊丝

STELLOY 12-G

CLASSIFICATION

EN 14700: T Co2
ASME IIC SFA 5.21 / AWS A 5.21: ERCCoCr-B

DESCRTPTION

• 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°C200°C400°C600°C800°C
450 HB 420HB 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.
