Product Detail

Product Tags

Hastelloy B3 Flanges is a high-performance nickel-based alloy that exhibits excellent corrosion resistance in harsh environments, high strength, and excellent mechanical properties at both high and low temperatures. Hastelloy B3 Flanges are commonly used in high-temperature and high-pressure applications, such as in the chemical and petrochemical industries, aerospace and defense, and marine applications.

Hastelloy B3Flanges come in different types and dimensions, including weld-neck flanges, slip-on flanges, socket-weld flanges, blind flanges, and lap joint flanges. These flanges are available in various sizes and pressure ratings, ranging from ½” to 48″ and class 150 to class 2500.

Hastelloy B3 Flanges are designed to withstand high temperatures and pressure, making them suitable for use in critical applications. These flanges are also resistant to pitting, crevice corrosion, and intergranular attack, making them ideal for use in harsh environments.
