AWS A5.34 ENICrMo3Ti-4 This wire is designed to match the composition and properties of alloy625. Originally developed to give high temperature strength and structural stability, alloy 625 is also widely used for its resistance to general corrosion, pitting, crevice and stress corrosion cracking in severe chloride media. These properties are conferred by high levels of chromium, molybdenum, and niobium, which also raise strength to the highest amongst standard nickel-base alloys. Service properties are useful from -269°C to above 1000°C.
