Product Description
Product Description
Hastelloy plates are suitable for use in a variety of chemical industries containing oxidizing and reducing media. The higher molybdenum and chromium contents make 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 only a few materials resistant to moisture chlorine, hypochlorite and chlorine dioxide solution. It has high concentration of chloride solution such as ferric chloride and copper chloride. Significant corrosion resistance.
Application areas
heat exchangers, bellows compensators, chemical equipment, flue gas desulfurization and denitrification, paper industry, aerospace applications, acidic environments.
Classification
Hastelloyalloy is mainly divided into three series of B, C and G. It is mainly used in the case of iron-based Cr-Ni or Cr-Ni-Mo stainless steel, non-metallic materials and other strong corrosive media.
Hastelloy grade
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)
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).

They are widely used in demanding environments including heat exchangers, bellows compensators, chemical equipment, flue gas desulfurization and denitrification systems, the paper industry, aerospace applications, and acidic environments.
How is the Hastelloy alloy classified?
Hastelloy alloy is primarily classified into three main series: B, C, and G. They are designed for applications involving strong corrosive media where standard iron-based Cr-Ni or Cr-Ni-Mo stainless steels are insufficient.
What are the common surface finishes for stainless steel sheets and their uses?
Common finishes include 2B (general purpose), No.1 & No.4 (ornaments, kitchen utensils, and food equipment), HL (elevators and building doors), BA (mirror-like reflexivity for kitchen apparatus), and 8K (high-reflectivity mirror finish).
How do chemical elements like Chromium and Molybdenum affect alloy performance?
Chromium (Cr) enhances hardness, tensile strength, toughness, and provides wear and corrosion resistance. Molybdenum (Mo) increases strength, hardness, toughness, and improves overall machinability and corrosion resistance.
