Machining Material Stellite 151

Stellite 151 is a Cobalt-based heat resistant superalloy (HRSA) material with a Machinability rating of 6% and Hardness of 46 HRC.

Stellite 151 has 65% cobalt, 1% nickel and additional alloying elements per the below table.

Cobalt-based alloys excel in wear resistance and chemical stability in harsh and hot conditions. Therefore, they are mainly used in valves and fittings in an acidic environment and medical implants such as artificial hip joints. In this sub-group, the material standards also define the allowed hardness range, and hardness is a significant factor affecting the machinability (besides the chemical composition). Cobalt-based alloys are the most challenging to machine superalloy sub-group with a poor machinability rating

Superalloys should be machined with a positive and sharp cutting edges. Geometries that are suitable for austenitic stainless steel will also work well on HRSA. However, quality manufacturers will have in their catalogs additional geometries that are specifically designed for these challenging materials.

Summery:

  • For general Turning of Material Stellite 151 at stable conditions use a grade with a Very Hard substrate and PVD coating.
  • For general Milling use a grade with a Semi Hard substrate and PVD coating.
  • For detailed carbide grades recommendations, check the Below Chart, or use the Grades Wizrad.
  • Recommended Cutting speed range for turning at stable conditions is 70 - 100 [SFM] / 20 - 30 [m/min].
  • Recommended Cutting speed range for milling with stable clamping and short overhang is 50 - 70 [SFM] / 15 - 20 [m/min]
  • For detailed cutting speed recomendations, check the Below Table, or use our Speed and Feed Calculator.
