Incoloy 800H/800HT Plates are known globally under various international standards. In the United States, they meet ASTM B409 and ASME SB409 specifications. In Europe, these plates are recognized under EN 1.4958 and 1.4959. The German equivalent is W.Nr. 1.4958/1.4959, while in Japan they align with JIS NCF 800H/800HT. The UK refers to these grades as BS 3076 NA15, and in Russia, they are known as ХН35ВТ (KHN35VT). This wide recognition ensures their compatibility and compliance in projects across global markets.

The core advantage of Incoloy 800H/800HT Plates lies in their ability to maintain strength and resist oxidation and carburization even at temperatures exceeding 1100°F (600°C). They exhibit high creep and stress rupture strength, making them ideal for pressure vessels and piping systems. The metallurgical stability of these plates ensures minimal distortion and cracking during thermal cycling, which is vital in industrial processes involving repeated heating and cooling. Their corrosion resistance in acidic and oxidizing environments makes them versatile and reliable for a wide range of heavy-duty applications.

• High tensile, creep, and rupture properties at elevated temperatures
• Excellent resistance to chloride-ion stress-corrosion cracking
• Nonmagnetic and having good weldability and fabricability
• High fatigue and oxidation resistance – High service life with low maintenance needs
