Hastelloy C276 ®
Hastelloy C276 is a nickel-molybdenum-chromium alloy that exhibits a high resistance to corrosion in severe and harsh environments. Hastelloy C-276 also has an excellent resistance to pitting and stress-corrosion cracking. As a wire mesh or wire cloth, it can be commonly used in pulp and paper industries, as well as in pollution control and chemical processing applications.

Inconel—currently registered as a trademark of the Specialty Metals Corporation—is a nickel-chromium alloy that offers excellent resistance to both corrosion and high temperatures. As a result, it is commonly used in a wide range of severe environments. In woven wire mesh or woven wire cloth form, Inconel may be used in chemical processing, pressure valve and heat exchange applications. Inconel 600, Inconel 601(with added Aluminum) and Inconel 625 (with added Molybdenum and Niobium) are commonly requested and available meshes; the difference between each of these originates in their individual chemical composition. The addition of certain elements will impact its characteristics in certain environments.

Composed primarily of Molybdenum (99.95%) with other trace elements, Molybdenum is an extremely versatile metal that can be used in high-temperature environments. As a woven wire mesh, Molybdenum exhibits excellent ductility and a high melting point. It can commonly be used in heating elements and electronic applications.
Nichrome A, also referred to as Nichrome 80-20, is comprised primarily of Nickel and Chromium. Due to its resistance to oxidation and its stability at high temperatures, this alloy is commonly used in electrical industry applications and other applications where high temperature resistance is important.

Titanium is a transition metal that is lustrous, silver-white in color and exhibits low density and high strength. In the wire mesh industry, there are two generally specified types of titanium – grade 1 and grade 2 – and both offer extremely high levels of corrosion resistance. Grade 1 Titanium and Grade 2 Titanium are considered commercial pure as they both are comprised of 99+% titanium, with trace elements of nitrogen, carbon, hydrogen, iron and oxygen.
Titanium is a popular metal for use in a wide array of industries, including aerospace, automotive, chemical processing, marine and medical due to many of its unique characteristics.
Tungsten is an extremely hard metallic element that can be woven into wire mesh and wire cloth. Tungsten has an extremely high melting point and is corrosion resistance in many harsh environments.
Trademarked under the name Kanthal –a family of iron-chromium-aluminum alloys—FeCrAlY is a special alloy that is normally only available through custom manufacturing. As the name indicates, it is comprised of Iron (Fe), Chromium (Cr), Aluminum (Al) and Yttrium (Y). The trace amount of Yttrium inhibits scaling.
Typically, applications include those in high temperature and/or highly corrosive environments.
Uncommon Stainless Steel Alloys
T-304 L SS – Usually a special order requirement, T-304 L SS woven wire mesh, due to its low carbon content, is oftentimes specified in welding applications.
T-316 L SS – Usually a special order requirement, T-316 L SS woven wire mesh, due to its low carbon content, is oftentimes specified in welding applications.
T-310 SS – Generally speaking, T-310 SS wire mesh is custom manufactured. It combines excellent high temperature properties with good ductility and weld-ability. It is usually reserved for high temperature service and has excellent toughness.
T-321 SS –T-321 SS wire mesh is usually a custom manufactured item, and as an austenitic 18/8 steel, it is stabilized by titanium and offers similar resistance to general corrosion as T-304 SS. Typical uses may include oil-refinery equipment and welded pressure vessels.
T-347 SS –T-347 SS wire mesh is usually a custom manufactured item, and as an austenitic 18/8 steel, it is stabilized by niobium and tantalum. These elements slightly improve corrosion resistance in certain environments. Typical uses may include high temperature gaskets and chemical product equipment.
T-430 SS –T-430 SS wire mesh usually requires custom manufacturing. It is a basic ferritic non-heat treatable stainless steel and offers good corrosion and oxidation resistance. Typical industrial applications may include plant equipment and oil-refinery equipment.
