A102（E308-16）It is a Cr19Ni10 stainless steel welding rod with titanium calcium coating. Fused metal has good mechanical properties and resistance to intergranular corrosion. It has excellent welding process performance and anti porosity performance, and the coating is resistant to redness and cracking. Can be used for both AC and DC.Used for welding corrosion-resistant stainless steel structures of 06Cr19Ni10 and 06Cr18Ni11Ti with working temperatures below 300 ℃.

A022（E316L-16）It is an ultra-low carbon Cr18Ni12Mo2 stainless steel electrode with titanium calcium coating. The deposited metal has a carbon content of ≤ 0.04%, and has good heat resistance, corrosion resistance, crack resistance, and porosity resistance. It has good operational process performance and good strength. Can be used for both AC and DC.

Used for welding equipment such as synthetic fibers and similar types of stainless steel structures, it can also be used for chromium stainless steel, composite steel, dissimilar steel, etc. that cannot be heat-treated after welding.

A302（E309-16）It is a Cr23Ni13 stainless steel welding rod with titanium calcium coating, and the deposited metal has good crack resistance and oxidation resistance. Can be used for both AC and DC, with good operational performance.

Used for welding the same type of stainless steel, stainless steel liningHeterogeneous steel (Cr19Ni9 and low carbon steel)And high chromium steel, high manganese steel, etc.
