Description of HAYNES 188 Flange

Alloy 188 is a cobalt-base superalloy with a unique combination of high and oxidation resistance, along with adequate ductility after prolonged exposure to the 1400-1600 °F temperature range. Cobalt alloys have an inherent advantage over the nickel base grades in high-temperature creep. Alloy 188 is a solid solution strengthened by a 14% tungsten addition, and further by M6CC and M23C6 carbides.

HAYNES 188 Flange FAQs

Q1: What is HAYNES 188 Bar?

HAYNES 188 Bar is a high-temperature, cobalt-based superalloy known for its excellent high-temperature strength, oxidation resistance, and thermal stability. It is commonly used in the form of bars for various high-stress applications.

Q2: What machining considerations are there for HAYNES 188 Bar?

Cutting Tools: Use carbide or ceramic cutting tools for machining.
Coolant: Use appropriate coolant to minimize heat generation during machining.
Speed and Feed Rates: Adjust speed and feed rates to accommodate the material's high strength and work-hardening characteristics.

Q3: How is HAYNES 188 Bar typically processed?

Hot Working: Can be hot worked at temperatures between 1177°C (2150°F) and 982°C (1800°F).
Cold Working: Limited cold working can be performed, but it is generally challenging due to the material's high strength.
Heat Treatment: Solution annealing is typically performed at around 1177°C (2150°F) followed by rapid cooling.
