Description

The general corrosion properties of NiCr21Mo6Cu with the material number 2.4641 are comparable with those of NiCr21Mo (material number 2.4858). It possesses a good resistance to reducing and oxidizing mediums and, due to the high Mo-content, it also is resistant to pitting in strongly chlorine-polluted mediums. Furthermore, the material is virtually insensitive to stress cracking corrosion. Among other things, it is applied in the production of phosphoric acid, in the offshore technology and in flue-gas washing devices. In the new edition of the DIN 17744 : 2002-09, the material is not contained any more.
