inpower Penetrating Hastelloy oil-free screw vacuum pump can be applied in weakly acidic environments, weakly alkaline environments, weakly oxidizing environments, high dust environments, high water vapor environments, etc., and has good stability. Hastelloy is a nickel based corrosion-resistant alloy, mainly divided into two categories: nickel chromium alloy and nickel chromium molybdenum alloy. Hastelloy alloy has good corrosion resistance and thermal stability, and is widely used in aviation, chemical fields, and other industries.
Hastelloy grades include the following grades:
HASTELLOY B-2 nickel molybdenum alloy has excellent corrosion resistance in reducing environments.
The upgraded version of HASTELLOY B-3 B-2 has excellent corrosion resistance to hydrochloric acid at any temperature and concentration. HASTELLOY C-4 has good thermal stability, good toughness and corrosion resistance at 650-1040 degrees Celsius.
Hastelloy alloy
HASTELLOY C-22 has better resistance to uniform corrosion in oxidizing media than C-4 and C-276, and excellent resistance to localized corrosion
HASTELLOY C-276 has good resistance to oxidative and moderate reducing corrosion, and excellent resistance to stress corrosion.
HASTELLOY C-2000 is the most comprehensive corrosion-resistant alloy with excellent resistance to uniform corrosion in both oxidizing and reducing environments.
The upgraded product of HASTELLOY G-35 G-30 has better corrosion resistance and thermal stability. HASTELLOY G-30 is a high chromium nickel based alloy that performs well in phosphoric acid and other strongly oxidizing mixed acid media. HASTELLOY X combines high strength, antioxidant properties, and easy processing;
Each of the above grades has specific chemical composition and mechanical properties, each with its own strengths, and cannot be generalized about the characteristics of Hastelloy alloys.
InPower will select different Hastelloy materials based on your usage environment to better meet your process requirements.
