STELLOY 6-O
EN 14700: TCo2
ASME IIC SFA 5.21 / AWS A 5.21: ERCCoCr-A
DIN 85551: MSG20-GF-40-CTZ
1 Former classification replaced by EN 14700
• Cobalt base tubular wire for self shielded bl arc hardsurfacing
• Exceptional resistance to bl-to-bl wear in corrosive media at high temperatures, to erosion and to thermal shocks
• STELLOY 6-O is used for hardsurfacing parts undergoing the single or combined effects of bl-to-bl wear, abrasion, temperatures ranging from RT to 800°C, impact and corrosive environments.
Examples
Used extensively on valve seats of diesel engines, cams, chainsaw bars, hot shear blades, cold bing rolls and hot bing rolls, for hot rolling reinforcing bar, pump parts and components in hot zinc baths.

High temperature hardness:
| 420 HB | 360 HB | 330 HB | 240 HB | 140 HB |
High deb rates and low dilution are facilitated by pulsed current
High heat bs favour lower hardness
