Nickel Alloy Gh5188 / Gh188 / Haynes Alloy No. 188/Ha188/ Unsr30188 / Kcn22W / High Temperature Alloy Forged Alloy Steel Round bar & Rods
GH5188 solution-strengthening cobalt-based superalloy, adding 14%
tungsten solid solution strengthening, makes the alloy have
excellent high-temperature thermal strength, adding high content of
chromium and trace lanthanum, so that the alloy has good
high-temperature oxidation resistance, and has Satisfactory
forming, welding and other process properties, suitable for
manufacturing aero-engine parts that require high strength below
980°C and anti-oxidation below 1100°C. It can also be used on
aerospace engines and space shuttles. It can produce and supply
various deformed products, such as sheet, medium plate, strip, bar,
forging, wire and precision casting.
1.1 GH5188 (GH188) material grade GH5188 (GH188).
1.2 GH5188 (GH188) similar grades Haynes Alloy No.188 (HA188),
UNSR30188 (USA), KCN22W (France).
