304 304S Stainless Steel Welding Rod Wire ER308 SUS304 WNR 1.4301 Diameter 08 to 50 mm Corrosion Resistant High Strength
Product Description
304 / 304S stainless steel welding rod/wire (also known as ER308, ER308L, SUS304, SUS304L, WNR 1.4301, 1.4307, SS304, 18Cr-8Ni) is a high-quality austenitic stainless steel filler material designed for welding 304 stainless steel and similar alloys.
It provides excellent corrosion resistance, good mechanical strength, and stable weld performance.
Widely used in chemical equipment, food processing machinery, piping, pressure vessels, kitchen equipment, and general stainless steel fabrication.
304S is the low-carbon variant, optimized to reduce sensitization and intergranular corrosion during welding.
