Hastelloy steel's Classification

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

Classification of Hastelloy steel

At present, it is mainly divided into three series of B, C and G. In the strong corrosive mediumIt ,if the Cr-Ni or Cr-Ni-Mo stainless steel can't work well ,the hastelloy steel will be used. In order to improve the corrosion resistance and cold and hot processing properties of Hastelloy,Hastelloy has undergone three major improvements, and its development process is as follows:

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)

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