A232
Description:
A232 is a titanium calcium type Cr18Ni12Mo2V stainless steel electrodes, due to the deposited metal contains V, it has good heat resistance and crack resistance. Has excellent welding performance, AC and DC can be used.
use:
06Cr19Ni10 and 06Cr17Ni12Mo2 stainless steel welded general heat-resistant and have a certain corrosion resistance.
