AWS A5.4 E318-16
Description:
AWS E318-16 is a kind of low-carbon Cr18Ni12Mo2Nb stainless steel electrode containing Nb stabilizer with lime-titania type coating. The deposited metal has better intercrystalline corrosion-resistance than that of AWS E316-16 and AWS E316-15.It has excellent welding performance. AC/DC.
Application:
Used for welding key 0Cr18Ni12Mo2,00Cr17Ni14Mo2,etc.stainless steel,such as urea synthesis towers,vinylon equipment, etc.which work in strong corrosive mediums.
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.
