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.

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 308L MIG wire used for?

308 stainless steel welding alloy is most frequently used for base metals of similar composition. It is used for welding metals of similar composition, such as 201,202, 301, 302, 304, 305 and 308 (and L Series). 308 is available for GMAW (MIG), GTAW (TIG), FCAW and SMAW welding processes.

What is 308L welding wire used for?

INERTROD 308L is used for the welding of 304 and 304L grade stainless steel. The weld metal has good corrosion resistance properties, including intergranular attack from a range of liquid media at service temperatures <300°C.

Can I use 308 instead 316?

Types of Welding Rod or Wire So you could weld 304 Stainless Steel with a 308 or 316 Rod/Wire, but you shouldn’t weld 316 with a 308 Rod/Wire.

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.

Can you use 308L on mild steel?

Always consult with the manufacturer of the base material or seek the expert advice of the filler metal manufacturer. If you are welding mild steel to stainless the recommended alloy is 309L or 309Lsi. This is true even if the stainless base material is 304, 308 or even 316.

What E308 16?

E308-16 is designed for welding of the following 18-8 stainless steel types: 301, 302, 304 and 308. The weld deposit has the proper chemical content and balance for satisfactory welding of type 308, and therefore is suitable for welding 18-8 types of lower alloy content.

What is the difference between 308 and 304?

There is such a minor difference in the make up between these 2 that it’s hard to give you a detailed difference, other than the fact 308 has a slightly higher Nickel content than 304, about 1 to 2% max. Where you will find the difference is in the maliability of 304 v 308.

What is 308L-16 welding rod used for?

Type 308L-16 is used extensively for welding of chemical plant equipment and may be used successfully for welding types 321 and 347 steel grades. E308L-16 minimizes the formation of chromium carbides in the weld metal.

What does E316 16 tell the welder?

E316-16 electrodes are designed for the welding to type 316 chromium-nickel steel. This alloy contains 2% to 3% molybdenum is addition to sufficient chromium and nickel to render is austenitic.

Can you put 308 heads on a 304?

The crank has a slightly shorter stroke hence 304 not 308 so 304 pistons have different pin height to suit this but is no problem so long as you dont try to fit 308 pistons to a 304 crank. You would have to change the cam to a 308 cam for your heads as said previously.
