Basic material
Stainless steel
S235JR (ST37-2) plastic-coated steel serves as a basic material, Rilsan-coated, approved for drinking water. Conforms to KTW requirements [offi cial German recommendation concerning the levels of polymers in drinking water] as recommended by the German Federal Department of Health.
S235JR (ST37-2) galvanized steel serves as a basic material, only suitable to a limited extent for drinking water, to be used for fl ange connections only.
Properties and suitability
Stainless steel of various qualities depending on groundwater condition and temperature
M No. 1.4301 (X5CrNi18-10), AISI 304 This type of steel is resistant to water and slightly polluted waste water as well as weak organic and inorganic acids. Generally, it is resistant to a pH value up to approx. 4.5 in aggressive substances low in chloride.
M No. 1.4541 (X6CrNiTi18-10), AISI 351 This type of steel has excellent resistance properties to a variety of aggressive media. Furthermore, this material is characterised by good ductility.
M No. 1.4571 (X6CrNiMoTi17-12-2), AISI 316TiSimilar properties as 1.4404 but with guaranteed resistance to intergranular corrosion due to an increased titanium content.
Additional materials on request
