, comparable to Hastelloy® X Alloy
NASHX (UNS N06002) is a nickel-chromium-iron-molybdenum alloy with outstanding strength and oxidation resistance in temperatures reaching as high as 1200℃. With superior workability and weldability as well, it is excellent for use in gas turbine members as well as various heating furnace parts. Nippon Yakin supplies this product in plate, sheet, and strip forms.

| Workability | We recommend using a range of 982 to 1177℃ for hot working NASHX. NASHX can also be easily cold worked. Note that a greater force is required to work NASHX than standard austenitic stainless steels. Solution treatment should be applied after working to obtain favorable creep properties. |
| Weldability | Such techniques as TIG, MIG and shield metal arc welding can be used for NASHX as with standard austenitic stainless steels. Before welding, the weld surface should be cleaned off oxidizing scales as well as oil and dirt. |
| Heat Treatment | The recommended solution heat treatment temperature is between 1149 and 1177℃, the range stipulated in SAE AMS 5536L. Rapid cooling is required after heat treatment to prevent precipitates. |
| Applications | Gas turbine parts, Furnace parts, Semiconductor manufacturing equipment. |
