In order to improve the corrosion resistance and cold and hot processing properties of Hastelloy tubes, the Hastelloy tube 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).
