Application areas | Aerospace, Plant engineering and construction, Chemical industry, Wood industry, Mechanical engineering, Oil industry, Paper industry, Sports and leisure industry, Ship building | |
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 | Percipitation hardened P1070 | |
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. |
