What is ER308 welding rod used for?

WW308 is used to MIG, and submerged arc welding of un-stabilized stainless steels such as Types 301, 302, 304, 305, 308. This filler metal is the most popular grade among stainless steels, used for general purpose applications where corrosion conditions are moderate.

What does ER308 stand for?

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.

When should I use 308L 309l or 316L filler metal?

For high temperature applications such as in the electrical power industry, the high carbon 308H electrode provides better creep resistance than does 308L. 316L (including ER316LSi) filler metal should be used with 316L and 316 base metals. CF-8M and CF-3M are the cast equivalents of 316 and 316L, respectively.

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 er308 and er308l?

Alloy ER 308L is ideal for welding Types 304L, 321 and 347. This classification is the same as alloy ER 308, except for the carbon content. The carbon content is held to a maximum of 0.03% to reduce the possibility of intergranular carbide precipitation.

What is the difference between er308 and ER308L?

What does the L mean in stainless steel?

Low carbon
Low carbon or “L” grades are used to prevent or delay sensitisation of stainless steel at elevated temperatures and the resulting lower corrosion resistance.

What is the difference between 308L and 309L?

And 2) the 309 has a higher ferrite percentage than the 308. A typical 309 can have a FN of approximately 12-18 FN, while the 308 is usually approximately 4-9 FN. Ferrite is beneficial in counteracting the possibility of hot cracking, or solifidication cracking.

What is the difference between ER308 and ER308L?
