The composition of S32760 steel plates mainly includes iron (FE), chromium (CR), nickel (Ni), molybdenum (MO), copper (CU) and other elements. Among them, the high content of chromium and nickel is the key element of double -phase stainless steel.
Two -phase stainless steel is a special stainless steel. Its tissue consists of two phases: iron body and Austenite, so it is called "double -phase" stainless steel. Among them, ferrite has good strength and corrosion resistance, while Austenite has good plasticity and corrosion resistance.
The tissue ratio of dual -phase stainless steel can be controlled by adjusting the chemical composition and thermal treatment process, so that the proportion of the two phases can achieve the best performance balance. Usually, the content of Olympic A medium in double-phase stainless steel is between 30%-70%.
Double -phase stainless steel has the following characteristics:
1. High intensity: Double -phase stainless steel has high tensile strength and yield strength, and can withstand greater force and pressure.
2. Good corrosion resistance: Double -phase stainless steel has excellent corrosion resistance and can resist the erosion of a variety of corrosive media, including the corrosion of acid, alkali, salt water, and high temperature and high pressure.
3. Good plasticity and weldability: Double -phase stainless steel has good plasticity and weldability, which is convenient for various processing and connection operations during the manufacturing process.
4. High temperature resistance: Double -phase stainless steel has good high temperature stability and antioxidant performance, and can maintain good mechanical properties and durability in high temperature environments.
5. Good strength-tough balance: Double-phase stainless steel has a good strength-tough balance, and can still maintain good toughness at low temperature. Two-phase stainless steel is a special stainless steel with high strength, corrosion resistance and plasticity. It is composed of two phases and Austenite, which has a wide range of application prospects. As a double -phase stainless steel, S32760 steel plate combines its excellent performance characteristics and is suitable for engineering fields that require higher intensity and corrosion resistance.
