AWS A5.4 E347-16
Description:
AWS E347-16 is a kind of Cr19Ni10Nb stainless steel electrode containing Nb stabilizer with lime-titania type coating. It has excellent intercrystalline corrosion-resistance, mechanical properties, welding performance and blowhole-resistance. The coating is red-resistant and crack-resistant. AC/DC.
Application:
Used for welding key corrosion-resistant 0Cr19Ni11Ti stainless steel containing Ti stabilizer.
Instruction:
1.The electrodes should be baked under 200-250ºC for an hour before welding.
2.Direct current had better be used and the current should not be too strong.
