What is 308 welding rod used for?

What is 308 welding rod 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.

What electrodes work best for stainless steel?

A 309 or 312 SMAW electrode is a good choice for stick welding stainless steel, especially for maintenance or repair applications. It offers high cracking resistance and good strength, and typically can join stainless steel already in service, even if the specific material grade isn’t known.

What is the difference between 308 and 309 stainless wire?

308 vs 309. The 2 main advantages of using a 309 instead of a 308 when joining a stainless steel to another steel is 1) the higher chemistry,Cr=22.0-25.0 and Ni=12.0-14.0 for the 309, as opposed to Cr=18.0-21.0 and Ni=9.0-11.0 for the 308. And 2) the 309 has a higher ferrite percentage than the 308.

What Tungsten is used for stainless steel?

What color Tungsten should be used for stainless steel? The thoriated red electrode is ideal for stainless steel welds. It provides the optimal heat generation, bead formation, and weld penetration to give smoother welds.

What happens if you weld 316 with 308?

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. A lot of Mig and Tig Wire may be 308LSi & 316LSi, this denotes Low Carbon and added Silicon. Adding Silicon will make the molten weld metal slightly more fluid and so flow better.

Can you weld stainless to carbon with 308 Rod?

In many cases some of these materials need to be welded to other types. Once very common situation, especially in automotive applications is welding carbon steel to stainless. This is true even if the stainless base material is 304, 308 or even 316.

What is the best tungsten for stainless steel?

Do you need special rods to weld stainless steel?

Types of Welding Rod or Wire The general rule with Welding Stainless Steel is to weld it with either the same grade of Welding Rod, Tig Wire or Mig Wire, or a higher grade. 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.

Is 308 stainless to stainless?

308 stainless steel is the second-most widely used type of stainless steel and is often used to weld on 304 stainless steel, the most commonly produced type of steel.
