FAQ：
Q1: How do we guarantee the quality of our products?
A1: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.
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.

The resulting corrosion can be visually evaluated and compared against standard criteria. 2. Electrochemical Testing: Electrochemical techniques such as potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) are widely used to study the corrosion behavior of special steel. These methods involve measuring the current and potential responses of the steel in various corrosive solutions to determine the corrosion rate and other electrochemical parameters. 3. Immersion Testing: In this method, the special steel is immersed in a specific corrosive solution for a predetermined period. The solution can be acidic, alkaline, or even simulated seawater depending on the intended application. The weight loss or surface damage caused by corrosion is then measured and compared to evaluate the steel's corrosion resistance. 4. Crevice Corrosion Testing: This technique focuses on evaluating the susceptibility of special steel to crevice corrosion, which occurs in confined spaces or gaps. A crevice is created between the steel specimen and another material, and a corrosive solution is introduced into the crevice. The severity of crevice corrosion is assessed by measuring the depth of attack or using electrochemical methods. 5. Intergranular Corrosion Testing: Special steel can be prone to intergranular corrosion, which occurs along the grain boundaries. Tests like the Strauss test or the Huey test are conducted to determine the steel's susceptibility to this form of corrosion. These tests involve immersing the steel in a corrosive solution at elevated temperatures and assessing the extent of intergranular attack. 6. Accelerated Testing: Accelerated corrosion testing methods aim to simulate long-term corrosion effects within a shorter time frame. Techniques like cyclic corrosion testing, which includes alternating exposure to various corrosive environments, can provide valuable insights into the steel's performance under realistic conditions in a shorter time period. It is important to note that the selection of the corrosion testing method depends on the specific requirements, intended application, and environmental factors that the special steel will be exposed to.
