AWS Class ER312
ASME SFA 5.9
ER312 is a filler metal that has a microstructure that gives off a two-phase weld deposit, creating a weld metal that is highly resistant to cracks and fissures. ER312 is good to weld with metals of dissimilar composition and dissimilar metals, such as carbon steel, especially metals that have a high content of nickel. This alloy has a high content of chromium, thus providing good corrosion oxidation resistance at higher temperatures.
