308L

Description

Rod for base materials in 304L with silicon
These rods are used for welding 18/8 stainless steels. The main applications include the food industry, pharmaceutical equipment, and general fabrication. Typical service temperatures range from -100 °C to 400 °C. The higher silicon content compared to standard 308L increases the weld pool fluidity and improves bead appearance. A higher silicon content enhances wettability and allows for faster wire feed speeds compared to standard 308L products.

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.
