1.4301
HuaNickel 1.4301 is used as a building material up to 1500°F. Slight zooming starts at about 1200°F. 1.4301 has a minimum carbon content of 0.04% and a particle size of ASTM 7 or coarse. It has general corrosion resistance similar to mild steel HuaNickel1.4301. However, there is carbide precipitation in the heat-affected zone (HAZ) of the weld. Weldments may be susceptible to HAZ intergranular corrosion and polysulfuric acid stress corrosion cracking in oxidizing acid environments. Carbide precipitation is harmless to high temperature mechanical properties. 1.430122Cr 11Ni filler wire (ER308) or overlay electrode (E308) for welding. Most hot jobs do not require post-weld heat treatment.
