A172 stainless steel welding electrode
Model GB/T: E307-16 Equivalent to AWS: E307-16
Description: Titanium-calcium stainless steel welding electrode, used in both directions and has excellent crack resistance.
Application: Used for welding ASTM307 steel and other dissimilar steels, and also used for surfacing welding of impact-resistant, corrosion-resistant steel and transition layers, such as high manganese steel and quench hardening steel.
A202 stainless steel welding electrode
Model GB/T: E316-16 Equivalent to AWS: E316-16
Description: Calcium titanium type Cr18Ni12Mo2 stainless steel electrode, due to the addition of molybdenum to the weld metal, has good corrosion resistance, heat resistance and crack resistance, especially good against chloride ion pitting corrosion, can be used in both AC and DC, and has excellent processability.
Application: 0Cr18Ni12Mo2 stainless steel used for working in organic acid and inorganic acid media.
A212 stainless steel welding electrode
Model GB/T: E318-16 Equivalent to AWS: E318-16
Description: Titanium-calcium type niobium-containing Cr18Ni12MoNb stainless steel electrode, the deposited metal has better resistance to intergranular corrosion than A202 and A207. It can be used in both directions and has excellent process performance.
Application: Used for important 0Cr18Ni12Mo2, 0Cr17Ni14Mo2 and other stainless steels, such as urea synthesis towers, vinylon equipment and other components that are exposed to strong corrosive media.
A222 stainless steel welding electrode
Model GB/T: E317MoCu-16
Description: Titanium calcium type Cr19Ni13Mo2Cu stainless steel electrode, because the deposited metal contains copper, has better corrosion resistance than other stainless steel electrodes in acidic media, can be used in both AC and DC, and has excellent process performance.
Application: Used for the same type of copper-containing stainless steel equipment.
A232 stainless steel welding electrode
Model GB/T: E318 V-16
Description: Calcium titanium type Cr18Ni12Mo2V stainless steel welding electrode, used for both AC and DC.
