What is a 308 16 welding rod?

E308/308L-16 is an extra low carbon electrode for the welding of type 304L, 321, and 347 stainless steels. The controlled ferrite in the weld deposit gives excellent notch toughness at cryogenic temperatures.

What is the difference between 308 and 309 welding rod?

Both the 308 and the 309 have an All-Weld-Metal Tensile requirement of 80ksi minimum, but the 309 is usually recommended for welding stainless to dissimilar metals. To add to what Chuck has said, the higher chromium content in 309 promotes the formation of ferrite and increases resistance to oxidation and corrosion.

When would you use a 308 welding rod?

ER308L (including ER308LSi) is predominately used on austenitic stainless steels, such as types 301, 302, 304, 305 and cast alloys CF-8 and CF-3. For high temperature applications such as in the electrical power industry, the high carbon 308H electrode provides better creep resistance than does 308L.

What is the difference between 308 and 308L welding rod?

ER308/308L is used for welding types 304, 304L, 308, and 308L stainless steels. It is very similar to type 308 but has a carbon content held to a max of . 03% to avoid carbide precipitation. This product can also be used for welding types 321 and 347 stainless steels.

Can you use 308 to weld 304?

To weld Type 304 stainless, use Type 308 filler, as the additional alloying elements in Type 308 will better stabilize the weld area. However, 308L is also an acceptable filler.

What is 309 filler rod used for?

309 Tig Rod was designed to weld stainless steel to carbon steel and still have a strong ductile weld that can hold up to heating and cooling cycles.

What is the difference between 308L and 308LSi?

GEN 308LSi has the same chemical composition as GEN 308, except the higher silicon content. It is suitable for welding stainless steel type 304 and 308. Welding process can be done at a higher speed than GEN 308 and GEN 308L due to improved wettability of weld metal.

Can I use 308L on carbon steel?

A 308 filler would yield a deposit that when mixed with carbon steel would be similar to a 410 stainless deposit. This would be a weld deposit that may be too brittle for the application.
