A022
Description:
A022 is a titanium calcium-based ultra-low carbon Cr18Ni12Mo2 stainless steel electrodes, the deposited metal carbon content ≤ 0.04%, has good heat resistance, corrosion resistance and crack resistance, anti-stomatal performance, good operating performance, medicine Skin red, good strength. AC and DC can be used.
use:
For the welding of synthetic fibers and other equipment and the same type of stainless steel structure can also be used after welding can not be heat treatment of chromium stainless steel and composite steel, dissimilar steel.
