The materials used for wedge-shaped steel wire screens (also known as wedge wire screens or V-shaped wire screens) vary, mainly depending on the application, corrosion resistance requirements, and cost. According to the latest publicly available information (as of March 2026), common materials include:
Stainless Steel Series
304, 304L: General-purpose austenitic stainless steel, resistant to general corrosion, suitable for water treatment, food processing, chemical industries, and other conventional environments.
316, 316L: Molybdenum-containing stainless steel, with stronger resistance to chloride ion corrosion, suitable for seawater, acid and alkali media, and marine engineering.
321, 309: Suitable for high-temperature applications or applications requiring high resistance to intergranular corrosion.
Duplex stainless steel (e.g., 2205): Combines high strength with good corrosion resistance, used in harsh oil and gas environments.
904L, Hastelloy: Used in extreme corrosive environments such as strong acids, strong alkalis, or high-concentration chlorides.
Carbon Steel and Surface-Treated Variants:
Low-Carbon Steel Wire: Low cost; suitable for non-corrosive environments (e.g., dry solid-liquid separation, coal washing).
Galvanized Iron Wire: Provides basic rust protection via a zinc coating, though its durability is lower than that of stainless steel.
Other Metal Materials (Customizable upon request):
Such as imported high-strength stainless steel, titanium alloys, etc., for use in specialized operating conditions.
