At present, stainless steel welded pipe has been accepted by more and more industries. It is common in light industry, pharmaceutical, papermaking, sewage treatment, water supply, machinery and other fields. Now the automobile muffler is also made of stainless steel welded pipe. Is it 304 or 409 stainless steel welded pipe?

Stainless steel welded pipes for automotive mufflers are commonly found in two materials, 304 and 409 stainless steel.

304 stainless steel muffler is more corrosion resistant and high temperature resistant. The maximum is up to 650 degrees.

409 stainless steel mufflers are easy to rust and corrosion resistant. The same temperature can be as high as 650 degrees.

304 advantages:

1, as a car exhaust pipe, 304 stainless steel will be better. Because the maximum temperature at the exhaust port of an automobile engine is also less than 650 degrees. 409 and 304 are satisfied. However, 304 corrosion resistance is very good. In particular, it is suitable for the humid and hot climate in the south.

2, price, 304 stainless steel is 409, 2 times more. The performance is certainly much better than 409L

Good cars have already started using 304 stainless steel as an exhaust pipe. It must be a trend. Of course。 If you want to buy cheap, buy 409 stainless steel welded pipe is not bad.
