Product Description
STELLOY – 6G X 1.6mm
CLASSIFICATION
EN 14700 : T Co2
ASME IIC SFA 5.21 / AWS A 5.21: ERCCoCr-A
DESCRIPTION
Cobalt base tubular wire for gas shielded metal arc hardsurfacingExceptional resistance to metal-to-metal wear in corrosive media at high temperatures, to erosion and tothermal shocks
APPLICATIONS
Stelloy 6-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, im pact and corrosive environments.
Examples
Used extensively on valve seats of diesel engines, cams, chainsaw bars, hot shear blades, cold forming rolls
and hot forming rolls, for hot rolling reinforcing bar, pump parts and components in hot zinc baths.

High deposition rates and low dilution are facilitated by pulsed current
High heat inputs favour lower hardness
