Material Properties & Machinability Profile
Hastelloy C-276 is classified as a Nickel-Molybdenum-Chromium Superalloy widely specified for mission-critical components requiring Sour-gas petrochemical scrubbers, chlorine dioxide bleach reactors, and nuclear waste processing valves..
Engineering Kinematics & Cutting Parameters
Material Hardness : 200-240 HB.Recommended Cutting Speed ($V_c$) : 20 - 35 m/min with dedicated substrate coatings.Chip Load ($f_z$) : Maintained between 0.04 - 0.10 mm/tooth to prevent tool rubbing or excessive mechanical shock.Machinability Challenge : Immunity to wet chlorine and stress-corrosion cracking; severe work hardening requires rigid setups and heavy chip load control.Tooling Strategy : Employs high-pressure flood coolant (>= 30 bar) and micro-grain carbide or specialized inserts with positive rake geometries.
