AWS Class ER16-8-2 Welding Wire

The ER16-8-2 wire is an austenitic stainless steel filler wire, typically made up of 15–17% chromium, 7–9% nickel, 1.5–2.5% molybdenum, and 1.5–2.5% manganese, along with controlled amounts of carbon, silicon, and nitrogen. This specific composition provides excellent resistance to thermal fatigue and stress corrosion cracking, while ensuring the weld metal remains tough even in sub-zero temperatures. It boasts a tensile strength of around 75–85 ksi and offers outstanding metallurgical stability when exposed to thermal shock and high-temperature conditions.

What is AWS Class ER16-8-2 Welding Wire?

AWS Class ER16-8-2 Welding Wire is a special type of stainless steel filler made for welding heat-resistant stainless steels. It has a mix of 15-17% Chromium (Cr), 7-9% Nickel (Ni), 1-2% Molybdenum (Mo), 0.06-0.10% Carbon (C), 1.0-2.5% Manganese (Mn), 0.30-0.65% Silicon (Si), up to 0.03% Phosphorus (P), and up to 0.02% Sulfur (S). This balanced combination gives it good strength, helps it resist oxidation, and keeps it strong at high temperatures. ER16-8-2 is often used for welding kinds like 304H and 347H in high-temperature tasks. It helps to create strong welds and lowers the chance of cracking while keeping its strength in very hot conditions.
