Haynes188 alloy plate is a solid-solution strengthened cobalt-based high-temperature alloy. Adding 14% tungsten solid-solution strengthening gives the alloy excellent high-temperature thermal strength. Adding a higher content of chromium and trace amounts of lanthanum gives the alloy good high-temperature oxidation resistance. , and has satisfactory process properties such as forming and welding, and is suitable for manufacturing parts for aero engines that require high strength below 980°C and oxidation resistance below 1100°C.

Haynes 188 alloy platesare widely used in the manufacture of high-temperature components for gas turbines and missiles, such as combustion chambers, tail nozzles, and heat exchangers in the nuclear energy industry.
High-temperature components such as aeroengine combustion chamber flame tubes and guide vanes made of Haynes 188 alloy plates have passed long-term test runs and have been put into production. In the manufacturing process of parts processed from Haynes 188 alloy plates, any process (such as heat treatment, welding, etc.) should prevent carburization and copper contamination to avoid damaging the mechanical properties and corrosion resistance of the alloy.
Haynes188 high temperature alloyheat treatment specifications:
Haynes 188 alloy is typically solution heat treated at 2125-2175°F (1163-1191°C) and rapidly cooled or water quenched to obtain properties. Annealing at temperatures below the solution heat treatment temperature will produce some carbide precipitation in alloy Haynes 188, which may affect the properties of the alloy.
Wuxi Walmay Metal Co., Ltdcan produce and supply various deformed products, such as thin plates, medium plates, strips, bars, forgings, wire rods and precision castings.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
Wuxi Walmay Metal Co,Ltd is a comprehensive processing group of Alloy Steel、Forged Parts Fitting、Titanium Alloy、Stainless Steel、Special Welding Wireseries， and more than 800 specifications.
Our group has been engaged in the domestic and global market for more than ten years with rich steel experience and can offer professional advice for customers inapplications with different materials.
