A052
Description:
A052 is titanium calcium type ultra-low carbon stainless steel Cr18Ni24Mo5 electrode, the weld metal is resistant to acid-containing, acetic acid medium point corrosion and chloride ion corrosion resistance, corrosion resistance than A022 electrode is superior. Has excellent welding performance, AC and DC can be used.
use:
For chemical resistance to sulfuric acid, acetic acid, phosphate reactors, separators, at the same time can be used for seawater corrosion resistant steel (022Cr18Ni24Mo5) and dissimilar steel welding.
