Hastelloy grades include the following:
Hastelloy B-2 nickel molybdenum alloy has excellent corrosion resistance in reductive environment, upgraded version of Hastelloy B-3, B-2, and excellent corrosion resistance for hydrochloric acid at any temperature and concentration.
Hastelloy C-4 has good thermal stability and good toughness and corrosion resistance at 650-1040 ℃.
Hastelloy C-22 has better resistance to uniform corrosion in oxidizing medium than C-4 and C-276, and is locally resistant
Hastelloy alloy
Excellent corrosion resistance Hastelloy C-276 has good resistance to oxidation and medium reduction corrosion, and excellent stress corrosion resistance. Hastelloy C-2000 is the most comprehensive corrosion-resistant alloy with excellent uniform corrosion resistance in both oxidation and reduction environments.
The upgraded products of Hastelloy G-35 G-30 have better corrosion resistance and thermal stability. Hastelloy G-30 nickel base alloy with high chromium content has excellent performance in phosphoric acid and other strong oxidizing mixed acid medium.
Hastelloy x is characterized by comprehensive high strength, oxidation resistance and easy processing. Each of the above brands has specific chemical composition, mechanical properties and their own advantages. It is impossible to generalize the characteristics of Hastelloy alloy.
-
Hastelloy alloy is mainly divided into B, C and G series. It is mainly used in iron-based Cr Ni or Cr Ni Mo stainless steel, non-metallic materials and other occasions where strong corrosive media cannot be used.
Hastelloy brand
In order to improve the corrosion resistance, cold and hot working properties of Hastelloy, three major improvements have been made in Hastelloy. The development process is as follows:
Series B: 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)
The most widely used materials are n10665 (b-2), N10276 (C-276), n06022 (C-22), n06455 (C-4) and n06985 (G-3)
