2205 Stainless Steel is far superior to standard marine grade 316 and 316L.

2205 Stainless Steel has been developed over the last 10-20 years by metallurgists that required a stainless that was not only stronger than standard marine grade 316, but offered much better corrosion resistance. (2205 is commonly used for marine propeller shafts.)

2205 Stainless achieves almost twice the corrosion resistance to ordinary 316. This is due to added levels of Nickel, Chromium, Molybdenum and Nitrogen.

Features of 2205 are High Resistance to:

  • Fatigue corrosion
  • Stress corrosion cracking – especially in salt water
  • Chloride pitting and crevice corrosion – especially suited to salt water
  • Sulphide stress corrosion
  • High energy absorption
  • Low thermal expansion
  • Good weldability and workability

These reasons are why 2205 is heavily used in the commercial offshore seawater environment and is designated as the minimum requirement for such applications.

Unlike any other water strainer manufacturer in the world, ARCTIC STEEL has committed to manufacturing all cast stainless steel strainers with duplex 2205 stainless steel.

Arctic Steel strainers have a fully cast one-piece strainer body, eliminating the corrosion weaknesses inherent at welded joints.  To further enhance our strainers, all bodies and lids are electro polished, which removes surface contaminants, providing even greater resistance to corrosion and a unique chromium rich shine to our strainers.

Not only are the materials used, better than any other strainer in the World, the robust design and function of Arctic Steel strainers are second to none, providing all vessels with unrivalled performance and operational efficiency.
