308L

Description

Solid rod for 304L base materials
These consumables are used to weld 18/8 stainless steels. Mainly applications include food industries, pharmaceutical equipment and general fabrication. Typical service temperatures are -100°C to 400°C. Reduced carbon levels offer increased resistance to inter-granular corrosion. Very good corrosion resistance under fairly severe conditions, such as in oxidizing acids and cold or dilute reducing acids. The wire can also be used for welding titanium and niobium stabilized steels such as 321 and 347 when the construction is used at temperatures not exceeding 400°C.

Description

Application

Engineered for welding 18Cr/8Ni stainless steels, encompassing 301, 302, 303, nitrogen-bearing 304LN, and titanium-stabilized 321, these welding consumables offer versatile performance. They perform well in service temperatures ranging from -100°C to about 400°C, making them suitable for applications in food, brewery, pharmaceutical equipment, architectural and general fabrication, as well as nuclear engineering. It's important to note that these consumables, specifically 308L, are not recommended for elevated temperature structural applications involving 304/304H; refer to 308H for such applications. For cryogenic use at -196°C, consult 308LCF. No preheating is required, and the recommended maximum interpass temperature is 250°C, with no post-weld heat treatment necessary.

Alloy Type

308L austenitic stainless steels for joining 304L base materials.

Microstructure

Austenite with a controlled level of ferrite, normally in the range 3-12FN depending on the application.
