Stainless steel can also Non-standard Series Deep Groove Ball Bearings certain conditions. The surface of stainless steel is deposited with dust containing other metal elements or attachments of foreign metal particles. The decorative stainless steel surface must be cleaned and scrubbed frequently to remove attachments and eliminate external factors that cause modification. 2. Stainless steel has the ability to resist atmospheric oxidation---that is, it is not rusty, and it also has the ability to corrode in media containing acid, alkali and salt---that is, corrosion resistance. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), it will form sulfuric acid, nitric acid, and acetic acid liquid spots when encountering condensed water, causing chemical corrosion.Why does stainless steel rust? Why does stainless steel rust?

When brown rust spots (spots) appear on the surface of stainless steel pipes, people are surprised: 'Stainless steel does not rust, and rust is not stainless steel. In fact, this is a one-sided misconception about the lack of understanding of stainless steel. 2.. 4. The surface of stainless steel adheres to organic juice (such as melon, vegetable, noodle soup, sputum, etc. For example, 304 steel pipe has excellent anti-corrosion ability in a dry and clean atmosphere,

Commonly used equipment for smelting metals includes cupola, electric arc furnace, induction furnace, resistance furnace, reverberatory furnace, etc. Commonly used sand moulding core making equipment include high, medium and low pressure moulding machines, sand blasting machines, boxless injection moulding machines, core shooting machines, cold and hot core box machines, etc. Entering the 20th century, the rapid development of casting, one of the important factors is the advancement of product technology, requiring better mechanical and physical properties of castings, while still having good mechanical processing performance; another reason is the machinery industry itself and other The development of industries such as chemicals and instruments has created favorable material conditions for the foundry industry.

but when it is moved to a coastal area, it will quickly rust in sea fog containing a lot of salt; while 316 steel pipe has performance good. 3. 3. Once this film is continuously destroyed for some reason, oxygen atoms in the air or liquid will continuously infiltrate or iron atoms in the metal will continuously separate out, forming loose iron oxide, and the metal surface will continue to be rusted
