A002
Description:
A002 is a super-low carbon Cr19Ni10 stainless steel electrode with titanium calcium type coating. The carbon content of deposited metal is less than or equal to 0.04%, good intergranular corrosion resistance, good welding process performance, Good anti-porosity, AC and DC can be dual-use.
use:
For welding ultra-low carbon 022Cr19Ni10 stainless steel structure can also be used 06Cr18Ni11Ti operating temperature below 300 ℃ corrosion-resistant stainless steel structure, mainly for the manufacture of synthetic fibers, fertilizers, petroleum and other equipment.
