Installation Steps for Corrosion-Resistant Alloy Wire Mesh by Manufacturers

Corrosion-resistant alloy products are manufactured by many suppliers. Technological advancements have greatly improved product performance. However, to ensure safe and reliable use, please read the relevant instructions carefully before installation and operation.

Corrosion-Resistant Stainless Steel Wire Mesh

This category mainly includes:

• Standard 300-series stainless steels with atmospheric or seawater corrosion resistance, such as 304, 316L, 317L.
• Austenitic stainless steels with high corrosion resistance, such as 904L; duplex stainless steels such as 2205, 2507.
• Copper-containing corrosion-resistant alloys such as Alloy 20; 254 SMO (00Cr20Ni18Mo6CuN, S31254).

254 SMO is an austenitic stainless steel. With its high molybdenum content, it exhibits excellent resistance to pitting corrosion and crevice corrosion. This grade is designed for harsh environments such as seawater.

As a versatile material, 254 SMO is widely used in:

• Petroleum and petrochemical equipment, e.g., bellows in petrochemical units.
• Pulp and paper bleaching systems, e.g., pulp digesters, bleaching equipment, drums and press rolls for filters and washers.
• Flue gas desulfurization (FGD) systems in power plants, including absorber towers, flue ducts, baffle doors, internals, and spray systems.
• Offshore systems or seawater treatment, e.g., thin-walled condenser tubes cooled by seawater in power plants, desalination equipment, and equipment in stagnant seawater service.
• Desalination industry, e.g., salt production and demineralization equipment.

Nickel-Based Corrosion-Resistant Alloy Wire Mesh

Nickel-based alloy wire mesh offers high strength and good oxidation/corrosion resistance at 650–1000°C.

By performance, it is subdivided into:

nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, etc.

By matrix, high-temperature alloys are classified as:

nickel-based, cobalt-based, and iron-based high-temperature alloys. Nickel-based high-temperature alloys are often simply referred to as nickel-based alloys.

Heat-Resistant Alloys

1. Incoloy alloys

e.g., Incoloy 800, composition: 32Ni-21Cr-Ti, Al

• Inconel alloys

e.g., Inconel 600, composition: 73Ni-15Cr-Ti, Al

• Ni-Cr alloys

e.g., Cr20Ni80, composition: 80Ni-20Cr

• Cr-Ni stainless steels

e.g., 0Cr25Ni20, composition: 20Ni-25Cr

Corrosion-Resistant Alloys

1. Monel (Ni-Cu) alloys

e.g., Monel 400, composition: 63Ni-28Cu

• Ni-Cr-Mo alloys

e.g., Hastelloy C-276, composition: 56Ni-15Cr-16Mo

Typical Applications of Nickel-Based Corrosion-Resistant Alloys

1. Marine industry: offshore structures, seawater desalination, mariculture, seawater heat exchangers, etc.
2. Environmental protection: flue gas desulfurization in thermal power plants, wastewater treatment, etc.
3. Energy sector: nuclear power, comprehensive coal utilization, tidal power generation, etc.
4. Petrochemical industry: oil refining, chemical processing equipment, etc.
5. Food industry: salt production, soy sauce brewing, etc.

In the above fields, conventional stainless steel 304 is generally unsuitable. Special stainless steels and alloys are indispensable and irreplaceable.

In recent years, with rapid economic development and industrial upgrading, a growing number of projects demand higher-grade stainless steel products, driving increased demand for nickel-based alloys across industries.

Warm Tips

The development of corrosion-resistant alloy products relies on continuous technological progress, and modern products perform far better than older versions.

However, this does not mean they can be installed or operated casually.

Always follow the official manufacturer instructions for installation and use.
