ER-316L Stainless steel 1.4430 UNS31683

What is stainless steel ER 316L？

ER-316L is welded by semi-automatic technology with 100% Argon or 100% Helium shielding gas (TIG welding) to create a stable weld with little splash and a bright, smooth weld. TIG welding rod ER-316L is suitable for welding all kinds of vessels, including chemical tanks, load-bearing structures, acid-resistant equipment, and equipment in the medical and food industries.

Applications for ER 316L ステンレス鋼

• Sheet metal
• High pressure piping and tubing
• Use for welding similar alloys containing approximately 2% molybdenum
• Food Processing
• Pharmaceutical Processing
