DIN 1654-5 Grade X5CrNi18-12 Quenched Steel (+Q): Enhanced Austenitic Stability & Formability
Because of its higher Ni content compared standard type to X 5CrNi 18 10, steel X 5 CrNi 18 12 possesses a higher austenitic stability. This decreaes the cold strain hardening. The forming properties for cold heading and extrusion pressing are good even at high forming rates. However, one must be aware of the increased cold strain hardening compared to carbon steels. It is used for stainless steel screws, nuts and cold-extruded parts. It is used for corrosive damage from water, atmosphere and oxidizing acids of higher concentration and higher temperatrues in the chemical industry.
