Material 1.4529 (HCR)

The key properties of material 1.4529

Stainless steel 1.4529 HCR is characterized by its high resistance to local corrosion phenomena, such as crevice corrosion, pitting, or chlorine-induced stress corrosion cracking. It also demonstrates excellent mechanical properties and can be used in a wide temperature range. In contact with sulphuric or phosphoric acid, or chlorides and salts, it offers excellent resilience and resistance to wear.

Possible applications for 1.4529 stainless steel
in connection technology

The applications for 1.4529 in connection technology are very diverse. It is approved for use in pressure vessels at temperatures of –196° C
to 400° C and has been granted building inspectorate certification by DIBt, the technical authority for construction engineering in Germany.
It is particularly suitable for use in areas where work is carried out in which chlorides, salts and diluted sulphuric or phosphoric acids or seawater are used. For example, in the construction of swimming pools, its use is obligatory for attaching structural components.
Tragic accidents that occurred in the past due to chloride-induced stress corrosion cracking have certainly contributed to its obligatory use.
