Annular convoluted hoses & Stainless Steel 316/321 > Guidance For Corrosion Resistance of Hose and Fitting Materials


  Guidance For Corrosion Resistance of Hose
and Fitting Materials

This material suitabilty information may be used as a guide for the selection of Stainless Steel hose and for fittings material suitable for conveying the substances listed. However, this data should not be construed as advice to use or not to use without further testing or investigation since variations in service conditions can influence resistance to corrosion. Our technical department will be pleased to give further information on specific applications.

 
Interpretation of corrosion data
Group 1 = Resistant
Group 2 = Partially resistant
Group 3 = Non resistant
