Here's a dumb question. Is Kanthal SS?
Seeing as I'm no metallurgist, here's my layperson answer:
Kanthal heating wire and SS (Stainless Steel) heating wire are two different products. SS has become recently more popular because it can be used for temp control, whereas kanthal can not. I haven't tried SS myself yet, but my wife just informed me they got some in at her store.
I'll report back soon.
