PM Industries manufactures, supplies, and stocks AMS 5608 Udimet 188 Sheet Plate (UNS R30188). AMS 5608 is the aerospace material specification covering this cobalt-nickel-chromium-tungsten alloy in sheet and strip form. Udimet 188 and Haynes 188 are trade names for the same composition, and material certified to AMS 5608 satisfies procurement requirements under either designation. The specification defines chemistry, mechanical properties, heat treatment condition, and surface quality requirements for aerospace production.

Alloy 188 is a solid-solution strengthened cobalt superalloy developed specifically for sheet metal applications in gas turbine hot sections. The combination of cobalt base, high chromium for oxidation resistance, tungsten for solid-solution strengthening, and a small lanthanum addition for improved oxide scale adhesion produces a sheet alloy with excellent oxidation resistance and adequate strength at very high temperatures. It retains those properties in sheet form with better weldability and formability than many gamma-prime strengthened nickel superalloys, which is why it became the established material for fabricated combustor and hot-section sheet metal structures in aerospace gas turbines.

Oxidation resistance is the defining capability of alloy 188 in its primary applications. Combustor liners, transition ducts, and flame holders in gas turbine engines spend their service lives exposed to combustion gas flow at temperatures that would cause rapid oxidation failure in standard nickel alloys. The chromium content in alloy 188 provides a stable chromia scale, and the lanthanum addition is what keeps that scale adherent during the repeated heating and cooling cycles of engine operation. Every engine start and shutdown is a thermal cycle for the combustor hardware, and scale spalling during cooling exposes fresh metal to oxidation on the next heating cycle. The lanthanum reduces that spalling, which is why alloy 188 outlasts cobalt alloys without lanthanum in cyclic combustor service.

Weldability makes alloy 188 practical for the complex fabricated sheet metal structures of gas turbine combustors. Combustor liners and transition ducts involve many welds in multiple orientations and configurations. An alloy that is difficult to weld without cracking creates manufacturing challenges that affect yield, rework cost, and schedule. Alloy 188's solid-solution strengthening mechanism avoids the strain-age cracking susceptibility of gamma-prime alloys during post-weld heat treatment, making it more reliable for complex welded fabrications than Waspaloy or other high-gamma-prime alloys despite those alloys' higher pure strength.

Solid-solution strength at temperature is adequate for the structural requirements of combustor and transition duct components. These components carry thermal and pressure loads but are not rotating structural elements that carry the centrifugal loads of turbine discs. The solid-solution strength that tungsten provides covers the structural requirements of those applications within the alloy's temperature range.
