I recently found a brand new factory built aster Stirling that sells for $2000，this little jewish has never been steamed ，so I purchased it. But when I took it to my home，opened the steam chest, I found that the stainless steel fastening screw of one of the slide valves had severely rusted with half of it turning into mud, so I can’t remove it easily ,which made me curious about how this happened and why stainless steel also rusted like this.

There are others in the hobby that can repair the problem if she gets out of time if its beyond your skils to deal with the rusted remains. Newer stainless grub screws can be gotten from Aster to replace those. Not sure when Aster transitioned to stainless screws. This problem is common in the early models from them. I had to deal with this on a Reno. Thankfully after getting things apart, I was able to spin the remains out of the valve spindle rod. Ryan B over at Triple R Steam Services or your local Aster dealer if your overseas can help

Its possible the wrong set screws got put in that kits box or if factory built, the builder grabbed the wrong package of them and got regular steel vs stainless. Things happen.

I have read back in the day in Steam in the Garden magazine, that many capped one of the wicks to tame the burner a bit and help with water consumption.
