Corrosion Resistance Chart

The figures quoted in the table below based on BS 6501 – 2004 standard and present the following categories of resistance to corrosion:

Category 1 – recommended (excellent resistance)
Category 2 – partially resistant (not recommended for continuous use)
Category 3 – not recommended (for ANY use)

For solutions without any recommended hose materials (all 3s), Penflex makes hoses with Hastelloy C-276 (our 776 Series) and Inconel 625 (our 625 Series) which offer increased corrosion resistance. Contact us to discuss further if there’s a need for these alloys.
