Sandvik 2RK65 is high-alloy austenitic stainless steel characterized by very good resistance to general corrosion in sulphuric, phosphoric and acetic acid as well as very good resistance to pitting corrosion and stress corrosion cracking.

Applications
Sandvik 2RK65 is a multi-purpose material for use under severe corrosive conditions. This has been proven both by laboratory tests and by extensive operational experience with the steel.

Typical applications for Sandvik 2RK65 are found in oil refineries and within the chemical and petrochemical industry.

Sandvik 2RK65 is also used within the pulp and paper industry, the mineral and metallurgical industry, the food industry, in seawater cooling and in many other fields.

The grade is an excellent alternative to standard austenitic stainless steels in heat exchangers using high temperature water with chloride contamination.
