Q2: What makes stainless steel stainless?
A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.
Q3: Can stainless steel rust?
A3: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

- Q: How can steel round bars be protected from corrosion?
- Steel round bars can be protected from corrosion through various methods. One of the most common ways is by applying a protective coating such as paint or enamel. This coating acts as a barrier between the steel and the corrosive elements in the environment, preventing direct contact and reducing the chances of corrosion. Another effective method is through the use of galvanization. This involves coating the steel round bars with a layer of zinc. Zinc is a sacrificial metal, which means it corrodes more easily than steel. So, when the round bars are exposed to moisture or other corrosive substances, the zinc coating will corrode instead of the steel, providing an added layer of protection. Using stainless steel round bars is also a great way to prevent corrosion. Stainless steel contains a significant amount of chromium, which forms a passive layer on the surface of the steel. This passive layer acts as a shield, protecting the steel from corrosion caused by moisture or other corrosive agents. Regular maintenance and cleaning of the steel round bars is crucial in preventing corrosion. Removing dirt, dust, and other contaminants from the surface helps to maintain the protective coating or passive layer, if present. Additionally, keeping the round bars dry and storing them in a well-ventilated area can also help prevent corrosion. Lastly, proper handling and storage of steel round bars are important. They should be stored in a dry and covered area to prevent exposure to moisture and corrosive elements. Avoiding contact with other metals or materials that can cause galvanic corrosion is also essential. By implementing these protective measures, steel round bars can be effectively shielded from corrosion, ensuring their longevity and structural integrity.
