AWS A5.9
AWS Class ER410NiMo
UNS S41086

ER410NiMo is primarily made to weld castings and wrought material of similar composition. These metals were made to contain more nickel to get rid of ferrite in the microstructure. Interpass temperature greater than 300°F is required for this alloy. Also PWHT should not be greater than 1150°F as this could result in hardening. This alloy is often used in the production of turbines, propeller shafts, gears, etc in the offshore and hydropower industries.

Yield Strength: 118,500 psi
Tensile Strength: 92,000 psi
Elongation: 20%
(Properties listed above based on PWHT between 1100°F-1150°F for 1 hour)

Available in multiple sizes and diameters
