| Technical information We distinguish two types of stainless steel, ferritic and austenitic.
Ferritic stainless steel generally contains as an alloy approx. 12 - 18% chrome whereas austenitic stainless steel contains on the one hand 18% chrome and also at least 8% nickel.
Other possible alloys use molybdenum, manganese, silicon, tungsten, vanadium, cobalt, titanium and niobium.
The addition of alloys allows the desired chemical and physical characteristics to be obtained according to the use for which the final product is intended:
Heat resistance, Cold resistance, Ease of transformation, Mechanical resistance, Corrosion resistance.
In the field of water treatment we can only consider austenitic steels which are the only group displaying sufficiently high anti-corrosive characteristics.
But not just their resistance to corrosion plays a determining role, but equally their mechanical resistance, that is to say their suitability for milling.
These conditions cause us to limit our choice to a certain selection of stainless steels.
Our choice is limited to the following stainless steels:
-stainless-Nr. 1.4301 - X 5 CrNi 18 10
-stainless-Nr. 1.4541 - X 6 CrNiTi 18 10
-stainless-Nr. 1.4306 - X 2 CrNi 18 11
-stainless-Nr. 1.4307 - X 2 CrNi 18 9
-stainless-Nr. 1.4571 - X 6 Cr Ni Mo Ti 17 12 2
-stainless-Nr. 1.4404 - X 2 Cr Ni Mo 17 12 2
-stainless-Nr. 1.4435 - X 2 Cr Ni Mo 18 14 3
-stainless-Nr. 1.4462 - X 2 Cr Ni Mo N 22 5 3
These different qualities of stainless steel are available in the form of sheet metal of different thicknesses and different areas, or in the form of bars (round, square, flat), tubes or other profiles often at the request of customers.
