  • What aspects are included in the standards for cold rolled stainless steel strips?

    Dimensions and Tolerances: Standards for cold rolled stainless steel strip specify thickness, width, length, and allowable tolerance ranges. These parameters are very important to ensure product quality and suitability. Material composition: The standard will specify the material composition and chemical composition range used in stainless steel strips. These requirements ensure that the product has the required corrosion resistance and mechanical properties.

  • What is the corrosion resistance of 316l stainless steel strip?

    316L stainless steel strip is a low-carbon version of 316 stainless steel with good corrosion resistance, especially in high temperature and chlorine-containing environments. It is widely used in chemical, food processing, marine environment and medical equipment.

  • What effects does high temperature environment have on the performance of precision stainless steel strips?

    High temperature environment has the following effects on the performance of precision stainless steel strips: Reduced strength and hardness: In high temperature environment, the strength and hardness of precision stainless steel strips may decrease significantly. As the temperature increases, the grain structure of the steel may change, resulting in a decrease in the tensile strength, yield strength and hardness of the material. For some stainless steel alloys, the decrease in strength and hardness will be aggravated after exceeding a certain temperature.

  • Common corrosion pitting corrosion of precision stainless steel strip

    Stainless steel is steel that is not easy to rust. The main alloying element in stainless steel strips is Cr (chromium). Only when the Cr content reaches a certain value, the steel has corrosion resistance. The general Cr content of stainless steel strips is at least 10.5%. The corrosion resistance mechanism of the stainless steel strip is the passive film theory, that is, an extremely thin, firm and fine stable Cr-rich passivation film is formed on the surface to prevent oxygen atoms from continuing to infiltrate and oxidize, thereby achieving the ability to prevent corrosion.

  • What are the material key factors of stainless steel coil?

    Stainless steel coil plays a very important role in our daily life. From ships to trains to high-rise buildings, some important alloying elements can help stainless steel to get better performance in various application environments.

  • What factors will destroy the passivation film on the surface of 304 stainless steel plate?

    The passivation film on the surface of 304 stainless steel sheet is a protective oxide layer used to prevent stainless steel from corroding in the environment. The passivation film can be damaged by the following factors: Mechanical wear: External objects or friction can cause surface wear of the passivation film and reduce its protective effect.
