Stainless Steel Er308 308l Welding Wire AWS A5.9 1.6mm/2.0mm

Product Description

There are some differences between ER308 and ER308L stainless steel welding wires in chemical composition, performance and application range. The following is a detailed comparison of the two:

1. Chemical composition
ER308 stainless steel welding wire: The main component is 18Cr-8Ni, which contains about 18% chromium (Cr) and 8% nickel (Ni).

ER308L stainless steel welding wire: The main component is ultra-low C-18Cr-8Ni, that is, ultra-low carbon stainless steel welding wire, which contains similar chromium and nickel content as ER308, but lower carbon (C) content.

2. Performance characteristics
ER308 stainless steel welding wire:
The deposited metal has excellent mechanical properties and resistance to intergranular corrosion.
The crack resistance is also strong.

ER308L stainless steel welding wire:
Due to the lower carbon content, the deposited metal has better resistance to intergranular corrosion.
The welding process is smooth, the weld is smooth and flat, and the crack resistance is also good.
