Ha Alloy (Hastelloyalloy)
At present, mainly divided into B, C, G Three series, it is mainly used for iron-based Cr-ni or Cr-ni-mo stainless steel, non-metallic materials, such as the use of strong corrosive media occasions.
Halon Alloy Grade
In order to improve the corrosion resistance and the cold and heat-processing properties of the HA alloy, three major improvements have been made, and the 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 are the second-generation materials N10665 (B-2), N10276 (C-276), N06022 (C-22), N06455 (C-4) and N06985 (G-3).
