Stainless steel has a coating as well, but it is much easier to clean than normal mill scale. A quick once over with a resin disc will make it ready to weld. Stainless steel is much more resistant to rust and corrosion, so a heavy scale coating is not necessary to protect it. Stainless Pipes Fabbed With TIG Welding : pikrepo

Even though gas metal arc welding (GMAW) is generally considered to be a slagfree process, silicon islands present on the weld surface after welding are a normal (and largely unavoidable) byproduct of both solid and metalcored wires. Unfortunately, they can be troublesome when it comes to postweld cleanup. These islands are often small and hard to see, which can make it difficult to remove ...

Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of restoring abandoned mine areas, as well as decrease steel manufacturers' current waste footprint.

Because most stainless steel products received from the producing mill have been pickled, descaling is required only as a result of subsequent manufacturing operations. In evaluating the different methods for removing scale, it is well to keep in mind that scale on stainless steel is far more complex than scale formed on plain mild steel.
