Hastelloy C-22 in CNC Machining
Hastelloy C-22 is a strong and corrosion-resistant metal used in CNC machining. It is great for harsh environments because it resists rust and damage from chemicals.
Machining Hastelloy C-22 can be tough. It needs carbide tools, slow cutting speeds, and coolant to prevent tool damage. Using the right techniques helps get a smooth finish and prevents the metal from shifting during machining.
Hastelloy C-22 is mostly made of nickel, with chromium (20-22.5%), molybdenum (12.5-14.5%), iron (2-6%), cobalt (up to 2.5%), and tungsten (2.5-3.5%). These elements give it its strength and resistance.
