Alloy 330 Plates


Choudhary Metal is a leading stockist, supplier, importer, and exporter of Alloy 330 Plates and Nickel Alloy Plates. We offer these plates in a wide range of thicknesses from 3/16" (4.8mm) up to 1" (25.4mm), making them suitable for various heavy-duty industrial applications.

Our Alloy 330 Plates are widely used in industries such as chemical processing, petrochemical plants, thermal processing, and power generation, where high temperature strength and excellent corrosion resistance are essential.

Alloy 330 (UNS N08330) is a high-performance nickel-chromium-iron alloy known for its excellent resistance to oxidation, carburization, and thermal shock. It provides outstanding strength and stability at elevated temperatures and is comparable to Rolled Alloy 330, making it a preferred material for demanding industrial environments.

At Choudhary Metal, we ensure that our Alloy 330 Plates are manufactured using high-quality raw materials and advanced production technology, meeting international standards and customer-specific requirements.

Alloy 330 (USN08330) is an austenitic nickel-iron-chromium alloy evolved to offer first-rate resistance to carburizing and oxidizing atmospheres at elevated temperatures. With a nickel content of 34 to 37 percentages, the alloy stays fantastically proof against each chloride pressure corrosion cracking and embrittlement from the precipitation of sigma phase. It's far effortlessly fabricated using fashionable strategies for stainless-steel and nickel alloys. The alloy is used substantially in extended temperatures where resistance to the blended consequences of thermal biking and carburization is needed.
