Enter Hastelloy X, a superalloy that has become indispensable across various high-stakes industries. Known for its exceptional strength, remarkable resistance to oxidation and carburization, and superior performance under stress, Hastelloy X is the material of choice for demanding applications. In this article, we will dive into the technical intricacies of Hastelloy X sheets and plates, exploring their unique chemical composition and mechanical properties that make them stand out in the world of metallurgy. We will also uncover the diverse industries that rely on this versatile alloy, from aerospace to nuclear power, and how it meets the stringent requirements of each sector. Additionally, you’ll gain insights into the manufacturing processes that enable the production of Hastelloy X, including advanced techniques like additive manufacturing and precise welding methods.
Hastelloy X plate machining can be performed with conventional methods. Carbide tools are preferred, but high-speed steel cutting tools can also be used. Machinability is similar to that of austenitic stainless steels. The alloys is tough and, therefore, requires rigid fixturing, low cutting speeds and ample cutting fluids, either water-base or sulfochlorinated oil. Additionally, finish grinding is recommended when very close tolerances are required.
Similar to other nickel alloys we supply, such as Inconel 625 & Inconel 718, Hastelloy X plate has excellent welding ability, particularly in conjunction with gas-tungsten-arc (GTA), plasma-arc, and electron-beam welding. Generally, parent metal weld filler is used with welding carried out on solution heat treated material. Often post-weld heat treatment is employed to reduce residual weld shrinkage stresses. Strength and ductility are good in the as-welded condition, but a full post-weld solution heat treatment or lower temperature stress relief (1800F min) is often applied to obtain optimum properties (dimensional stability, fatigue life) in weldments.
Hastelloy X plate has very good forming ability when solution heat treated and can be cold formed by most of the common methods including drawing, rolling, bending, spinning, drop hammering, punching and shearing. The solution-treated condition is optimum for cold-forming operations because it provides minimum hardness and maximum ductility. Nevertheless, as a result of Hast X’s toughness and hardenability, relatively high energy levels and frequent intermediate solution treatments are required during severe cold forming operations. When performing simple bending operations on a brake press, Hastelloy X plate seldom requires lubrication. However, when performing severe forming, heavy-duty lubricants such as metallic soaps, chlorinated or sulfochlorinated oils are required. Additionally, land oil, caster oil or sperm oil lubricants are recommended for intermediate forming. Generally, after final cold working, parts should be solution treated to restore the optimum combination of mechanical properties and corrosion resistance.
Hastelloy X plate possesses excellent corrosion and oxidation resistance. It also has good sea water corrosion resistance and thus attractive for marine applications.
Hastelloy X plate wrought products are normally supplied by the mills in the solution heat treated condition, which provides the optimum combination of mechanical properties and corrosion resistance for practically all applications. Hastelloy X plate solution heat treatment consists of exposure to 2150 F followed by rapid cooling. The hold time at 2150 F varies with the section size of the product, size of load and furnace characteristics. A rule of thumb that provides acceptable results for the Hastelloy X plate being treated is to hold for 1 hour per inch of thickness. The cooling rate from 2150 to 1000 F or below should be rapid enough to prevent carbide precipitation, which decreases corrosion resistance and toughness for Hastelloy X sheet products. Rapid air cooling is adequate for this process, however, oil or water quenching is frequently necessary for heavier sections. If surface oxidation can be tolerated, the Hastelloy X plate solution treatment can be carried out in air or in the normal mixture of air and combustion products in gas-fired furnaces. Alternatively, oxidation can be minimized by the use of an exothermic furnace atmosphere or it can be almost entirely prevented by dry hydrogen, dry argon or vacuum atmospheres.
