Hastelloy wire mesh

Hastelloy wire mesh is also known as Hastelloy filter mesh, Hastelloy woven mesh, Hastelloy screen, Hastelloy square hole mesh, Hastelloy perforated plate, Hastelloy diamond mesh, Hastelloy metal wire mesh, Hastelloy filter mesh, etc.
Types of Hastelloy wire mesh: Hastelloy woven mesh, Hastelloy perforated mesh, Hastelloy steel plate mesh, Hastelloy welded mesh, Hastelloy crimped mesh, Hastelloy filler mesh, Hastelloy wire mesh demister, Hastelloy plain mesh, Hastelloy twill mesh, Hastelloy stainless steel mesh belt, etc. Hastelloy wire
mesh materials are mainly divided into three series: B, C, and G. They are mainly used in strong corrosive media that cannot be used in iron-based Cr-Ni or Cr-Ni-Mo stainless steel, non-metallic materials, etc.
Hastelloy wire mesh grades
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 are the second generation materials N10665(B-2), N10276(C-276), N06022(C-22), N06455(C-4) and N06985(G-3).
Hastelloy wire mesh grades include the following grades:
HASTELLOY B-2 Nickel-molybdenum alloy, with excellent corrosion resistance in reducing environment HASTELLOY B-3 The upgraded version of B-2, has excellent corrosion resistance to hydrochloric acid at any temperature and concentration.
HASTELLOY C-4 Good thermal stability, 650-1040 degrees Celsius has good toughness and corrosion resistance.
HASTELLOY C-22 has better uniform corrosion resistance than C-4 and C-276 in oxidizing media, and excellent local corrosion resistance. HASTELLOY C-276 has good resistance to oxidizing and moderate reducing corrosion, and excellent stress corrosion resistance. HASTELLOY C-2000 is the most comprehensive corrosion-resistant alloy, with excellent uniform corrosion resistance in both oxidizing and reducing environments.
HASTELLOY G-35 is an upgraded product of G-30, with better corrosion resistance and thermal stability. HASTELLOY G-30 is a high-chromium nickel-based alloy that performs well in phosphoric acid and other strong oxidizing mixed acid media.
HASTELLOY X has the characteristics of comprehensive high strength, oxidation resistance and easy processing. Each of the above grades has specific chemical composition, mechanical properties, and each has its own strengths. It is not possible to generalize what characteristics Hastelloy alloy has.
Application of Hastelloy Wire Mesh
Hastelloy wire mesh is suitable for various chemical industries containing oxidizing and reducing media. The higher molybdenum and chromium content makes the alloy resistant to chloride ion corrosion, and the tungsten element further improves the corrosion resistance. At the same time, C-276 Hastelloy alloy tube is one of the few materials that are resistant to corrosion by moist chlorine, hypochlorite and chlorine dioxide solutions, and has significant corrosion resistance to high-concentration chloride solutions such as ferric chloride and cupric chloride.
Application areas: heat exchangers, bellows compensators, chemical equipment, flue gas desulfurization and denitrification, papermaking industry, aerospace applications, and acidic environments.
