308L

Description

Solid wire 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

The 308L subfamily is specifically designed for the welding of 18/8 series stainless steels, including 301, 302, 303, and 304LN that contain nitrogen, as well as titanium-stabilized steels such as 321. The operating temperature range generally extends from -100°C to about 400°C. These consumables are ideal for a variety of applications ranging from the food sector to breweries, pharmaceutical equipment, construction and general building, to nuclear engineering. However, 308L products are not suitable for use with 304/304H steels in structural applications requiring high temperatures; for these needs, it is recommended to consult technical sheets C-10 and C-12. Similarly, for cryogenic applications (-196°C), it is advisable to refer to technical sheet B-37. No preheat is necessary and the maximum interpass temperature is set to 250°C; also, no post-weld heat treatment (PWHT) is required.

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.
