HAYNES 188 alloy

HAYNES 188 alloy is a solution hardened cobalt based super alloy that combines exceptional high temperature strength with exceptional resistance to oxidizing environments (up to 1095°C) and excellent resistance to corrosion and high temperature corrosion caused by sulfate deposition.

Haynes 188 alloy (UNS R30188) in brief:

HAYNES® 188 alloy is a cobalt-nickel-chromium-tungsten alloy that offers excellent high temperature strength, superior oxidation resistance up to 1095°C and thermal stability. This alloy is widely used in demanding gas turbine combustion engines, transition channels and afterburner components of military and civilian aircraft.

• Heat Resistant Alloy
• Cobalt-nickel-chromium-wofram alloy
• Combines high temperature strength with good resistance to oxidizing environments (up to 1095 degrees Celsius)
• Excellent resistance to sulfate and molten chloride salts.
• Good forming and welding properties (MIG and TIG)
• Often used in gas turbine engines 

Product description Haynes HTA - Haynes 188 alloy

This alloy is widely used in aircraft gas turbine engines. Although HAYNES 188 alloy is a very suitable alloy for that application, this alloy is increasingly being replaced by HAYNES 230® alloy in new demanding applications. HAYNES 188 alloy can be formed using various techniques, both cold and hot, and can be welded using standard techniques.

Availability Haynes 188 alloy

Haynes 188 alloy is mainly available in the form of plate, rod and welding consumables. Other shapes on request. Merrem & la Porte offers the possibility of cutting, sawing and plasma, waterjet or laser cutting.
