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 metal arc hardsurfacing
• Exceptional resistance to metal-to-metal 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 metal-to-metal 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 forming rolls and hot forming rolls, for hot rolling reinforcing bar, pump parts and components in hot zinc baths.

Structure: chromium and tungsten carbides in an austenitic type matrix

Hardness:

42 HRc

High temperature hardness:

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

Recovery: 90 %
