Corrosion properties
The good combination of high corrosion resistance and good mechanical properties makes Acidur 4542 suitable for use in marine environments. In standing seawater, however, Acidur 4542 is susceptible to crevice corrosion. If application in standing seawater cannot be excluded, additional protection (e.g. painting) must be applied.
General machinability
Acidur 4542 can be machined in both the solution annealed and hardened condition. The machinability of Acidur 4542 depends on the hardness
Heat Treatment
Hardening:1030-1055°C in oil, air - Percipitation hardening: 4 hr 550°C in air
Hot forming
It is formable at 900-1150°C
Processing history

Welding
To weld Acidur 4542, the condition of the base material must be taken into account. The copper is present in the material in a stable form and therefore does not promote hot cracking. In addition to setting optimum welding conditions, care must be taken to avoid undercuts or other welding defects that lead to the formation of a notch. After welding, the material must be solution annealed again within a very short time with subsequent ageing to prevent stress cracking.
