Material properties and areas of application

Grates made of stainless steel 1.4301 (V2A) or 1.4404 (V4A) are particularly well suited for applications that, in addition to heavy mechanical stresses, require resistance to chemicals such acidic or alkaline media, detergents and de-icing salt. Depending on the anticipated stresses, customers can choose between the alloy materials 1.4301 or 1.4404 for the grates. The use of V4A is recommended if consistent exposure is expected, for example in the case of swimming pools (fresh water). Even stainless steel of quality 1.4404 is not resistant to all chemical stresses such as hydrochloric and hydrofluoric acid or certain chloride and brine concentrations. In certain cases, this also applies to seawater pools. The suitability of a proposed floor drain system must be verified based on the anticipated chemical, mechanical and/or other stresses. Aggressive cleaning products should not be used.
