Introduction:

A002 is a kind of Titanium calcium type coating with ultra-low carbon Cr19Ni10 stainless steel electrode. Carbon content of deposited metal is less than or equal to 0.04%. The intergranular corrosion resistance is good. Excellent welding performance and heat resistance, high strength coating, the porosity resistance is good. AC/DC both can be applied.

 

Uses:

Used for welding ultra-low-carbon Cr19Ni10 stainless steel structures, and also used for 06Cr18Ni11Ti corrosion-resistant stainless steel structures whose working temperature is lower than 300°C. Mainly used in the manufacture of synthetic fiber, chemical fertilizer, oil and other equipments
