Will stainless steel be completely corroded by concentrated sulfuric acid?
What metal is in stainless steel?
Pure hydrochloric acid, with pure nitric acid, hydrofluoric acid can dissolve stainless steel.
Three times the pure nitric acid and one time the pure hydrochloric acid is called aqua regia, and real gold can be dissolved, not to mention stainless steel.
Give it points!

Anonymous users2024-02-09Hello dear, aqua regia or ferric chloride hydrochloric acid solution is commonly used to control the corrosion time. Aqua regia is generally used to corrode stainless steel grain boundaries. The blackening is generally too serious when it comes to rotting celery.
Aqua regia's decay is much stronger than ferric chloride solution, it is recommended that you use the latter to try it first, inject acorns to observe the surface color after polishing, and you can clean it with a slight discoloration to observe whether it achieves your expected effect.

Anonymous users2024-02-08Stainless steel corrosion, the name of the monopoly industry should be attacked.
There are many etching formulas for stainless steel, some formulas are suitable for machine etching, some are suitable for manual etching, and some are suitable for small batches of proofing etching, so the formulas used in different situations are also different. Generally speaking, the most widely used formula for etching stainless steel is ferric chloride etching solution, which has a long life, is easy to control, and the etching effect of the potion is relatively mild, so this type of formula is very widely used. The specific recipe is as follows:
After the solid ferric chloride is dissolved with water, the Baumé degree is adjusted to 40-42 degrees, the amount of hydrochloric acid added is generally 2-3% of the total amount of liquid, and the etching temperature is room temperature - 50 degrees Celsius. The type of etching machine can be either splash or spray.

Stainless steel introduction:
The corrosion resistance of stainless steel decreases with the increase of carbon content, therefore, the carbon content of most stainless steels is low, the maximum is not exceeded, and the WC (carbon content) of some steels is even lower than that of e.g. 00Cr12).
The main alloying element in stainless steel is CR (chromium), and it is only when the CR content reaches a certain value that the steel is corrosion-resistant. Therefore, stainless steel generally has a cr (chromium) content of at least. Stainless steel also contains elements such as Ni, Ti, Mn, N, Nb, Mo, Si, and Cu.

To choose a cabinet tabletop, you should choose quartz. Although the stainless steel table top is also better in terms of high temperature and oil resistance, the overall decorative effect is relatively poor, and the stainless steel table top is prone to scratches and fine lines after a long time, which will affect the appearance and easily cause bacteria. For personal use, stainless steel machining is expensive, but it also has its obvious drawbacks. >>>More
