Alloy B3 Machinability

Back To Hastelloy Machinability

Nickel & cobalt base corrosion, temperature and wear-resistant alloys, such as Hastelloy B3, are classified as moderate to difficult when machining, however, it should be emphasized that these alloys can be machined using conventional production methods at satisfactory rates. During machining Alloy B3 work harden quickly, generate elevated heat during cutting, weld to the cutting tool surface and offer high resistance to metal removal due to their high shear strengths.

Applications
  • Chemical processes
  • Vacuum furnaces
  • Mechanical components in reducing environments
