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: Can stainless steel rust?
A2: 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 does the heat treatment process affect the properties of special steel?
- The properties of special steel are greatly affected by the heat treatment process. This process involves controlled heating and cooling of the steel to modify its microstructure and, as a result, its mechanical properties. To begin, heat treatment can increase the hardness of special steel. By heating the steel to a specific temperature and then rapidly cooling it through quenching, the steel undergoes a phase transformation that boosts its hardness. This is especially advantageous for applications that demand high strength and resistance to wear, such as cutting tools or bearings. Furthermore, heat treatment can enhance the toughness of special steel. By tempering the quenched steel at a lower temperature, the brittleness caused by rapid cooling can be minimized, leading to improved toughness and ability to withstand impacts. This is crucial in applications where the steel must endure sudden shocks or impacts, like in automotive or aerospace components. Moreover, heat treatment can also improve the overall strength of special steel. Through a combination of heating, cooling, and tempering processes, the steel's grain structure can be refined, resulting in increased strength and resistance to deformation. This is particularly critical for structural applications where the steel must withstand heavy loads or extreme conditions. Additionally, the heat treatment process can influence the corrosion resistance of special steel. By subjecting the steel to specific heat treatment cycles, the formation of certain phases or chemical compounds can be encouraged, leading to enhanced resistance against corrosion or oxidation. This is essential for applications exposed to harsh environments or corrosive substances, such as in marine or chemical industries. In conclusion, the heat treatment process is essential in modifying the properties of special steel. By carefully controlling the heating, cooling, and tempering cycles, the hardness, toughness, strength, and corrosion resistance of the steel can be significantly improved. This allows for the production of special steel with customized properties to meet the specific requirements of various industrial applications.
- Q: What are the different methods of protecting special steel against corrosion?
- There are several methods of protecting special steel against corrosion. These include applying protective coatings such as paints or epoxy, using sacrificial anodes or cathodic protection to redirect corrosion, employing corrosion inhibitors, and utilizing stainless steel or alloyed steel with higher corrosion resistance.
