Raw steel in the kitchen may first seem like a no-no. With all of that moisture and humidity generated by kitchen use, steel would eventually rust.
But if installed with a mind toward keeping it away from such moisture, and if properly sealed, you can have that industrial look of black steel in the kitchen. As a case in point, we're highlighting this accent wall in a Sonoma cottage kitchen.
The 1930's cottage renovation was designed by San Francisco's Antonio Martins. Paired with the black floors, this wall is a sharp detail that brings a little hard edge to the cottage's kitchen.

I love your oven/stove! What is it/where is it from? Thanks.
and un-sealed, you could embrace the rust as 'patina' - the way soapstone ages and gets more character.
i'm working on a project in which the kitchen cabinets will be faced with unfinished steel - so excited!
the stove looks like a 40's wedgewood or an o'keef and merrit. hard to tell from that angle. You can find them all day on craigslist in great shape for very little money and once you replace the safety valves they will be safe and work for 60 more years.
