Steel Properties
The 1.4541 is a chrome-nickel stainless steel with addition of titanium with increased hardness, elasticity, maintaining non-magnetic properties, resistance to intergranular corrosion and increased temperatures. It is worth mentioning about the very good impact strength maintained at low temperatures, sufficient ductility of the materials, as well as increased resistance to pitting and crevice corrosion due to the content of titanium in the chemical composition.
