Stainless Steel ER307 Filler Wire

Here are some of the general mechanical properties of stainless steel ER307 filler wire:

• Tensile strength: The tensile strength of ER307 filler wire is typically between 75,000 and 85,000 psi.
• Yield strength: The yield strength of ER307 filler wire is typically between 30,000 and 40,000 psi.
• Elongation: The elongation of ER307 filler wire is typically between 40% and 50%.
• Impact resistance: The impact resistance of ER307 filler wire is typically good at room temperature.

The mechanical properties of ER307 filler wire may be affected by factors such as the welding process, the cooling rate, and the heat treatment

Here are some of the general specifications for stainless steel ER307 filler wire:

• Diameter: ER307 filler wire is available in a range of diameters, including 0.035 inches, 0.045 inches, 0.063 inches, and 0.093 inches.
• Welding current: The recommended welding current for ER307 filler wire is between 70 and 120 amps.
• Welding positions: ER307 filler wire can be used in all welding positions.
• Shielding gas: A shielding gas is typically not required when using ER307 filler wire.
• Preheat temperature: A preheat temperature is generally not required when using ER307 filler wire.
• Interpass temperature: The interpass temperature should be kept as low as possible when using ER307 filler wire.
• Post-weld heat treatment: Post-weld heat treatment is generally not required when using ER307 filler wire.

It is important to note that these are general specifications and may vary depending on the manufacturer and the specific application.
