Weld stainless steel with these rods.

ER308L—ER308L rods are for 304 stainless steel. They create welds that hold even in cryogenic temperatures.

ER308LSi—ER308LSi rods are for 304 stainless steel. They have a higher silicon content than ER308L rods, so they flow more easily when melted and fill in more of the space between the two pieces of your weld. They’re also better where appearance matters because their welds are smoother.

ER309L—ER309L rods join different types of stainless steel. They’re also for use with steel.

ER309LSi—ER309LSi rods are for 309 stainless steel. They have a higher silicon content than ER309L rods, so they flow more easily when melted and fill in more of the space between the two pieces of your weld. They’re also better where appearance matters because their welds are smoother.

ER316L—ER316L rods are for 316 and 316L stainless steel.

ER316LSi—ER316LSi rods are for 316 stainless steel. They have a higher silicon content than ER316L rods, so they flow more easily when melted and fill in more of the space between the two pieces of your weld. They’re also better where appearance matters because their welds are smoother.

ER630—ER630 rods are for 17-4 PH stainless steel.
