KUNWU Stainless Steel TIG Welding Filler Rods ER316L 1/16" x 36"

Low carbon (0.03 % maximum) in this filler metal reduces the possibility of intergranular chromium carbide precipitation and thereby increases the resistance to intergranular corrosion without the use of stabilizers such as niobium or titanium.

The 2.5 % molybdenum content of 316L gives the weld deposit excellent corrosion resistance at elevated temperatures against “pitting” that may be caused by sulfuric, phosphoric and acetic acids.

ER316L is usually used to 18% chromium – 12% nickel – 2.5% molybdenum austenitic stainless steels such as 316 and 317 but with a low ferrite, it can also be used for welding 304/304L to 316/316L stainless steels in cryogenic service at temperatures down to -452 ℉ (-269 ℃).

Primarily used for welding low-carbon molybdenum-bearing austenitic alloys. Common applications include equipment that manufacturers rayon, dye, paper, ink, rubber, bleach, photographic chemicals and on the sealing faces of valves and fittings for acid, gas, water and steam equipment.

Description of ER316L

The nominal composition (wt.-%) of ER316 is 19 Cr, 12.5 Ni, and 2.5 Mo. This filler metal is used for welding Type 316 and similar alloys. It has been used successfully in certain applications involving special base metals for high-temperature service. The presence of molybdenum provides creep resistance at elevated temperatures and pitting resistance in a halide atmosphere.

Same except for the carbon content. Low carbon (0.03 percent maximum) in ER316L filler metal reduces the possibility of intergranular chromium carbide precipitation and thereby increases the resistance to intergranular corrosion without the use of stabilizers such as niobium or titanium.

ER316L filler metal is primarily used for welding low-carbon molybdenum-bearing austenitic alloys. This low-carbon alloy, however, is not as strong at elevated temperature as the niobium-stabilized alloys or Type ER316H.
