standard & specification

UNS N06455 C4

C4 = UNS N06455, is a relatively new Ni-Cr-Mo alloy with improved resistance at high temperatures. Even when used for a long period of time in the temperature range of 650 - 1050° Celsius, this alloy retains its high ductility and corrosion resistance; furthermore it is highly resistant to grain boundsary separation in the heat-treated zone influenced by welding. Thus it can be employed without heatretreatment. Techalloy C-4 is also highly resistant against stress corrosion cracking and oxidizing atmospheres at temperatures up to 1050° Celsius.
