FAQ:
Q1: How soon can we receive the product after purchase?
A1: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.
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 do steel flat bars perform in high-temperature oxidation conditions?
- Steel flat bars are known to perform well in conditions of high-temperature oxidation. Their resistance to oxidation, especially in the presence of oxygen, is well-documented. At elevated temperatures, a protective oxide layer forms on the surface of the steel flat bar. This layer is primarily composed of iron oxide and acts as a barrier to prevent further oxidation and corrosion, thereby preserving the integrity of the steel in high-temperature environments. Moreover, the composition of the steel is a determining factor in its performance under high-temperature oxidation conditions. Steel grades containing higher levels of chromium, such as stainless steel, exhibit even greater resistance to oxidation. This is due to the formation of a stable and protective chromium oxide layer on the surface, which acts as an additional barrier against oxidation. As a result, steel flat bars with higher chromium content demonstrate improved performance in high-temperature oxidation conditions. Nevertheless, it should be noted that prolonged exposure to extremely high temperatures or harsh oxidizing environments, as encountered in certain industrial processes, can still cause some degree of oxidation and degradation. Therefore, it is advisable to carefully consider the specific operating conditions and seek guidance from experts or engineers in order to select the appropriate steel grade or apply additional protective coatings, if necessary, to ensure optimal performance in high-temperature oxidation conditions.
- Q: How can I prevent rusting on steel flat bars?
- To prevent rusting on steel flat bars, you can apply a protective coating such as paint, varnish, or a rust-inhibiting primer. Additionally, keeping the bars dry and storing them in a moisture-free environment can help prevent rust formation. Regular cleaning and maintenance, including removing any dirt or debris that may trap moisture, will also contribute to preventing rust on steel flat bars.
- Q: Do steel flat bars have a specific thermal conductivity?
- Steel flat bars indeed possess a distinct thermal conductivity. This property gauges the material's proficiency in conducting heat. Steel is renowned for its elevated thermal conductivity, enabling the efficient transfer of heat. Nevertheless, the precise thermal conductivity of steel flat bars may fluctuate depending on the particular composition of the steel alloy employed, alongside additional factors like temperature and pressure.
