Hastelloy C-4 BAR/ SHEET/ BOLT/ Pipe

Common Trade Names: Hastelloy C-4 , Alloy C4, NS3305, UNS N06455 , W.Nr.2.4610

Hastelloyc C-4 is an austenitic low carbon nickel-molybdenum chromium alloy.
The main difference between HastelloyC-4 and other early developed alloys of similar chemical composition is the low carbon, ferrosilicate, and tungsten content.
Such chemical composition makes it show excellent stability at 650-1040℃, improve the ability to resist intergranular corrosion, under appropriate manufacturing conditions can avoid edge line corrosion sensitivity and weld heat affected zone corrosion.
