1.4568(X7CrNiAl17-7) is s a semi-austenitic precipitation hardening steel with high levels of Chromium and Nickel. It is characterized by high strength and hardness, excellent fatigue properties, minimal distortion upon heat treatment, good formability in the annealed condition, and good corrosion resistance.due to its exceptional mechanical properties, this steel is often used in aerospace applications. It is also used for manufacturing of flat springs, conical springs, washers, eyelets, and strain gauges. 1.4568(X7CrNiAl17-7) Stainless Steel can be used in industrial atmospheres and fresh water due to its good corrosion resistance, but it is not the best choice for use in salt water or reducing environments.

Brinell hardness (HB): (+AT) 255
Heat treatment of 1.4568 / X7CrNiAl17-7 forged steel parts is followings
Annealing
Annealing of stainless steel grade 1.4568 / X7CrNiAl17-7is performed at 1066°C (1950°F) for 3 min for every 0.1 inch (2.5 mm) of thickness, and then air cooled.
Aging
Stainless steel grade 1.4568 / X7CrNiAl17-7is solution annealed at 1177°C (2150°F) for 4 h and air cooled. Same step is performed at 1079°C (1975°F) for 4h and air cooled, then at 843°C (1550°F) for 24h and air cooled, and at 760°C (1400°F) for 16h and air cooled. This completed the precipitation hardening process. For excellent results and performance, the material should be clean and free from scale and impurities.
