2205 Stainless Steel has been developed for applications which require a stainless that was not only stronger than standard marine grade 316, but offers much better corrosion resistance.

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.

SISO and BISO 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.
