1.4567, X3CrNiCu18-9-4, 1.4560, X3CrNiCu19-9-2 – description

Austenitic stainless steel 18/8 with copper. This alloying addition makes it ductile for cold-heading and thread rolling applications, for example corrosion-resistant fasteners. Other applications are heat exchangers, coolers, tanks and pumps in paper and food processing plants, ship components and electronics. The steel has very good machinability and is very ductile, even in sub-zero temperature. It is not magnetic, nor it becomes magnetic after cold working. Usually delivered as wire.

The grade is basically the 304 / 1.4301 alloy enhanced by the addition of copper, which makes some characteristics very similar. 1.4567 alloy is, unlike 1.4560, resistant to intergranular corrosion in delivery condition and after welding; 1.4567 has also better resistance to corrosion in some reducing acid environments (e.g. contaiting H₂SO₄) than 1.4307. It is not resistant to halogen compounds and acids, such as hydrofluoric acid. To achieve maximum chemical resistance, the steel should be in annealed condition and elements should be passivated.
