Detailed introduction of ASTM B575 Alloy C276 Plates:


We can customize and process Hastelloy C276 Hot Rolled Plate and ASTM B575 UNS N10276 Cold Rolled Sheet according to customer requirements, with high standards and high quality. Main products: Nickel Alloy C-276 Plates,ASTM B575 Hastelloy C276 Plates,Alloy Hastelloy C276 Plate, Alloy C276 nickel alloy plate (UNS N10276).

Overview of Hastelloy Alloy C276 Sheet & Plate:

Hastelloy C-276 plate is also called NiMo16Cr15W, which belongs to nickel-molybdenum-chromium-iron-tungsten nickel-based alloy. It is the most corrosion-resistant kind of modern metal materials. It is mainly resistant to wet chlorine, various oxidizing chlorides, chloride salt solutions, acids and oxidizing salts, and has good corrosion resistance in low temperature and medium temperature hydrochloric acid. Therefore, in the past 30 years, in harsh corrosive environments, such as chemical industry, petrochemical industry, flue gas removal, pulp and paper, environmental protection and other industrial fields, it has been widely used.

NiMo16Cr15W (Hastelloy C-276) is generally considered to be the most versatile heat-resistant and corrosion-resistant alloy. We can provide NiMo16Cr15W forging materials according to DIN 17750. We use EAF + VOD-ESR melting method to melt NiMo16Cr15W materials, according to NiMo16Cr15W For the heat treatment of forgings, solution treatment and aging treatment can be carried out at the same time.

The hot working temperature range of Hastelloy C-276 alloy plate is 1200℃~950℃, and the cooling method is water cooling or rapid air cooling. In order to ensure the best anti-corrosion performance, heat treatment should be carried out after thermal processing, and the workpiece should be directly added to the heated heat treatment furnace.

The work hardening rate of Hastelloyc-276 alloy plate is greater than that of austenitic stainless steel, so processing equipment needs to be selected. The workpiece should be in a solution heat treatment state, and there should be intermediate annealing during the cold rolling process. If the cold rolling deformation is greater than 15%, the workpiece needs to be subjected to a second solution treatment.

The solution treatment temperature range of Hastelloyc-276 sheet is 1100℃~1160℃. The cooling method is water quenching, and rapid air cooling can also be used for materials with a thickness of less than 1.5mm. If air cooling is used, it should be cooled from 1000°C to 600°C within 2 minutes. During the heat treatment process, the workpiece must be kept clean.

The surface oxide of Hastelloyc-276 sheet and the adhesion of welding slag around the weld are stronger than stainless steel. It is recommended to use fine-grained abrasive belt or fine-grained grinding wheel for polishing. Before pickling with HNO3/HF mixed acid, the oxide film must be broken by sandblasting or grinding.

Machining of Hastelloy C-276 (N10276) alloy plate: Because it is sensitive to work hardening, it is advisable to use low cutting speed and heavy feed to process it in order to be machined under the cold hardened surface.
