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.

HuaNickel PRODEC 316/1.4404 is an improved version of the standard HuaNickel1.4404 for improved machinability and superior uniformity. PRODEC’s consistency and optimal machinability allow machining at higher speeds and feeds to produce high-quality parts at the lowest total cost. For automatic screw machines that require extensive processing, extensive processing should be considered.

HuaNickel 1.4438 is a molybdenum-containing austenitic stainless steel with improved corrosion resistance over HuaNickel 1.4301/1.4301L and 316/1.4404 stainless steels. The increased chromium, nickel and molybdenum content on 1.4404 stainless steel improves chloride pitting and general corrosion. By controlling nitrogen addition, HuaNickel 1.4438 can generally meet the mechanical properties of 317 straight grade while maintaining low carbon content.
