Hastelloy: A Comprehensive Guide to the Nickel-Based Alloys and Their Applications, Grades, and Products Offered by SSM
Introduction
Hastelloy is a nickel-based alloy that is known for its excellent corrosion resistance and high-temperature strength. It is a family of alloys that contains a variety of different elements to create unique material properties. In this article, we will introduce the material grade of hastelloy, its element composition, and mechanical properties. We will also discuss hastelloy products of different material grades, including pipe fittings, pipes, flanges, plates, bars, and more. Finally, we will introduce SSM, a leading manufacturer and supplier of hastelloy products.
Hastelloy Material Grade
The material grade of hastelloy is determined by the specific alloy composition. Hastelloy alloys contain a variety of different elements, including nickel, molybdenum, chromium, iron, cobalt, and tungsten. The different alloys are identified by a letter and number combination, with the letter indicating the family of alloys and the number indicating the specific alloy within that family.
Hastelloy alloys are grouped into four main families: C, B, G, and X. Each family contains a range of different alloys with unique material properties. Table 1 provides an overview of the material composition and mechanical properties of some commonly used hastelloy alloys.
