Hastelloy fasteners are suitable for various chemical industries containing oxidizing and reducing media. The higher content of molybdenum and chromium makes the alloy resistant to chloride ion corrosion, and the element of tungsten further improves the corrosion resistance. At the same time, C-276 alloy fasteners are one of the only materials that are resistant to corrosion by moist chlorine, hypochlorite and chlorine dioxide solutions. Significant corrosion resistance.
Application fields of Hastelloy fasteners, heat exchangers, bellows compensators, chemical equipment, flue gas desulfurization and denitrification, paper industry, aerospace applications, acidic environments
Hastelloy fastener materials (Hastelloyalloy) are mainly divided into three series, B, C, and G. It is mainly used for iron-based Cr-Ni or Cr-Ni-Mo stainless steel, non-metallic materials and other strong corrosive media that cannot be used. occasion.
Hastelloy grades
In order to improve the corrosion resistance and cold and hot workability of Hastelloy, Hastelloy has undergone three major improvements. 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)
