Aerospace Industry Nickel Baesd Alloy Hastelloy B2 Strip With High Temperature Performance

Product Introduction

Hastelloy B2 strip is a high-performance nickel-based high-temperature alloy strip widely used in the aerospace field. Its main components include nickel (balance), molybdenum (26.0-30.0%), iron (≤2.0%), chromium (≤1.0%), etc., which makes it perform well in high temperature and corrosive environments. Hastelloy B2 strip has excellent corrosion resistance, especially in reducing media such as various concentrations of hydrochloric acid, sulfuric acid, phosphoric acid and acetic acid. Its high-temperature performance is also excellent, with a maximum operating temperature of about 1000°C, which can ensure structural integrity and stability under extreme conditions.
In the aerospace field, Hastelloy B2 strip is used to manufacture key components such as engine components, combustion chambers, exhaust nozzles, etc. Its excellent corrosion resistance and high-temperature performance ensure the safety and reliability of aircraft and rockets in harsh environments. In addition, Hastelloy B2 strip also has good machinability and welding performance, and does not require preheating and post-heat treatment, which greatly simplifies the manufacturing process. These properties make Hastelloy B2 strip an indispensable high-performance material in the aerospace field, providing strong support for the development of modern aviation technology.
