Factors to Consider:

  • Environment: Consider the exposure conditions like temperature, humidity, and potential for corrosion.
  • Application: Analyze the mesh's function, such as filtration, security, or aesthetics.
  • Strength Requirements: Determine the level of strength and rigidity needed for the application.
  • Budgetary Constraints: Be mindful of the cost variations between different stainless steel grades.

Common Stainless Steel Wire Mesh Materials:

  • AISI 304 (SS304): The most widely used grade, offering good corrosion resistance and formability. Suitable for indoor environments, general filtration, and decorative applications.
  • AISI 316 (SS316): Includes molybdenum for enhanced corrosion resistance in saltwater, harsh chemicals, or extreme temperatures. Ideal for marine, chemical processing, and high-temperature applications.
  • AISI 304L (SS304L): Similar to 304 but with lower carbon content, improving weldability. A good choice for welded mesh projects requiring good corrosion resistance.
  • AISI 316L (SS316L): Similar to 316 but with lower carbon content, enhancing weldability while maintaining excellent corrosion resistance in harsh environments.
  • Special Alloys: For unique applications, specific alloys offer properties like high heat tolerance (Inconel) or superior chemical resistance (Hastelloy).

Choosing the Right Material:

  • Indoor applications with mild environments: AISI 304 (SS304) is a cost-effective and versatile choice.
  • Outdoor applications, marine environments, or high humidity: AISI 316 (SS316) provides superior corrosion resistance.
  • Welded mesh projects: AISI 304L (SS304L) or AISI 316L (SS316L) are preferred due to their improved weldability.
  • High-temperature or harsh chemical environments: Explore special alloys like Inconel or Hastelloy for optimal performance.

What is Stainless Steel?

With the addition of 11% or more chromium to steel, the alloy becomes non-staining under most conditions that corrode plain steel, thus the term stainless is applied.

 

Major SS Types and Properties:

Type 304 Wire Mesh:
Often referred to as "18-8" (18% chromium, 8% nickel) T-304 is the basic stainless alloy most commonly utilized for wire cloth weaving. It withstands outdoor exposure without rusting and resists oxidation at an elevated temperature up to Degrees Fahrenheit.
Typical 304 stainless wire cloth applications include use with chemicals, food products, pharmaceuticals and exposure to moisture.

Type 304 L Wire Mesh:
Type 304 L is very similar to T-304, the difference being the reduced carbon content for better weaving and secondary welding characteristics.

Type 309
A heat resistant alloy (23% chromium, 12% nickel) which is useful in temperatures up to Degrees Fahrenheit.

Type 310
Retains good strength and toughness at high temperatures and may be used to advantage where a combination of strength, toughness and oxidation resistance is essential. Where reducing or carburizing conditions are encountered at high temperatures, T-310 is preferred.

Type 310 has a coefficient of expansion slightly lower than most other chromium - nickel alloys.

Type 316
Stabilized by the addition of 2% molydbenum, T-316 is an "18-8" alloy.

Type 316 has better resistance to pitting corrosion than the other chromium-nickel stainless steels where brines, sulphur-bearing water or halogen salts, such as chlorides are present. A valuable property of T-316 is high creep strength at elevated temperatures. Other mechanical properties and fabricating characteristics are similar to T-304.

Stainless Steel Wire cloth woven of T-316 has extensive use in chemical processing when better corrosion resistance is required than the regular chromium-nickel types.

Type 316 L
Type 316 L is very similar to T-316, the difference being the reduced carbon content for better wire cloth weaving and secondary welding characteristics.

Differences Between 304 & 316 Grades of Stainless Steel

The Differences Between 304 and 316 Stainless Steel

All stainless steel is not made the same. Stainless steel is graded. The &#;grade&#; of stainless steel refers to its quality, durability, and temperature resistance. Deciphering what stainless steel you need is an important step in your next project involving stainless steel mesh. Type 304 and Type 316 stainless steel metal mesh are two of the most common types used but knowing the difference between the two is important.

304 Stainless Steel

Known as A2 stainless, 304 stainless steel is the most common of the stainless steel family. The most common form of 304 stainless steel is 18-8 or 18/8 stainless steel which contains 18 percent chromium and 8 percent nickel.

304 stainless steel mesh can withstand corrosion from most oxidizing acids. That durability makes this grade of stainless steel easy to sanitize, an ideal advantage for kitchen and food applications. 304 stainless steel is also common in buildings, decor, and site furnishings.

304 stainless steel is austenitic, meaning &#;&#;it is a solid solution of carbon in a nonmagnetic form of iron. This means this grade of metal mesh is non-magnetic and exhibits poor thermal and electrical conductivity. While it boasts excellent malleability and can be formed into required shapes, it also carries increased corrosion resistance when compared to regular steel. 304 is susceptible to corrosion from chloride solutions, or from saline environments like the coast.

316 Stainless Steel

316 stainless steel, also known as marine grade stainless or A4 stainless, is well-known for its increased resistance to corrosion and its superb abilities in salt-water and marine applications. While it comes with the same physical properties as 304 as well as similar utilitarian functions, the big difference is the incorporation of molybdenum, generally ranging from 2-3% by composition (although some specialty 300-series stainless steels can contain up to 7-8% molybdenum).

The increased nickel content and the inclusion of molybdenum make 316 stainless steel metal mesh a bit costlier than grade 304 but offer increased corrosion resistance compared to 304&#;particularly against chlorides and chlorinated solutions. 316 stainless steel is generally used whenever chemical processes and high-salinity environments warrant chloride-resistant features and due to its non-reactive traits, is also widely used in the manufacture of medical & surgical equipment.

Knowing the Difference between 304 and 316 Stainless Steel for Your Purchasing Decision

Austenitic stainless steels are known for their versatility. Lawrence Sintered Metals carries a full assortment of metal meshes in 304 and 316 stainless steel, as well as other grades. The benefits of stainless steel also come with age and proper care as low-maintenance requirements and long service life ensure that architectural and mechanical integrity will be non-issues for years to come.

If you&#;re planning on using stainless steel in saltwater environments, 316 is the proper alloy. If you&#;re looking for a durable alloy and superior corrosion resistance isn&#;t necessary, 304 stainless can work perfectly.
