Application
ER410 is used for welding types 403, 405, 410, 414, and 416. Also an overlay on carbon steels for corrosion, erosion and abrasion resistance. It is recommended using 350ºF preheat before welding.

Cr = 12.5 Mn = 0.45 S = 0.01
Ni = 0.35 Si = 0.39 Cu = 0.10

 

Mechanical Properties (R.T.) 
Yield Strength 78,500psi
Tensile Stength 89,000psi
Elongation 24%

Deposited All Weld Metal Properties
Data is typical for ER410 weld metal deposited by Mig using Argon + 2% oxygen as the shielding gas. Data on sub-arc is not presented, as sub-arc is dependent on the type of flux used.

Both Agglomerated and fused fluxes can be used for submerged arc welding.
Note: The chemical composition of the flux mainly affects the chemistry of the weld metal and consequently its corrosion resistance and Mechanical properties.
