what's the Hastelloy?

Hastelloy is a nickel-based corrosion-resistant alloy, which is mainly divided into two categories: nickel-chromium alloy and nickel-chromium-molybdenum alloy. Hastelloy has good corrosion resistance and thermal stability, and is mostly used in aviation and chemical fields.

Characteristics of Hastelloy

  1. In the state of oxidation and reduction, it has excellent corrosion resistance to most corrosive media.
  2. It has excellent resistance to pitting corrosion, crevice corrosion and stress cracking corrosion.

Classification of Hastelloy

Hastelloy alloy is currently mainly divided into three series: B, C, and G. It is mainly used in iron-based Cr-Ni or Cr-Ni-Mo stainless steel, non-metallic materials and other strong corrosive media occasions that cannot be used. In order to improve the corrosion resistance and cold and hot workability of Hastelloy, Hastelloy has undergone three major improvements. Its development process

B series: B→B-2(00Ni70Mo28)→B-3

C series: C→C-276(00Cr16Mo16W4)→C-4(00Cr16Mo16)→C-22(00Cr22Mo13W3)→C-2000(00Cr20Mo16)

G series: G→G-3 (00Cr22Ni48Mo7Cu)→G-30 (00Cr30Ni48Mo7Cu)

Currently the most widely used are the second generation materials N10665(B-2), N10276(C-276), N06022(C-22), N06455(C-4) and N06985(G-3)

Chemical Composition of Hastelloy

Different types of Hastelloy alloys have very different chemical compositions, but they are all dominated by nickel.

Chemical And Physical Properties

The mechanical properties of Hastelloy are very outstanding. It has the characteristics of high strength and high toughness, so it has certain difficulties in machining, and its strain hardening tendency is extremely strong. When the deformation rate reaches 15%, it is about 18-8 Twice as much as stainless steel. Hastelloy also has a medium temperature sensitization zone, and its sensitization tendency increases with the increase of deformation rate. When the temperature is high, Hastelloy is easy to absorb harmful elements, which reduces its mechanical properties and corrosion resistance. View our steel center here

Hastelloy Applications

Hastelloy plates are suitable for various chemical industries containing oxidizing and reducing media. The higher content of molybdenum and chromium makes the alloy resistant to chloride ion corrosion, and the tungsten element further improves the corrosion resistance. At the same time, C-276 Hastelloy tube is one of the only materials resistant to the corrosion of wet chlorine gas, hypochlorite and chlorine dioxide solutions. Significant corrosion resistance.

Application fields, heat exchangers, bellows compensators, chemical equipment, flue gas desulfurization and denitrification, paper industry, aerospace applications, acid environments.
