Main Technical Content: **Technical Requirements:** 1. **Grade and Chemical Composition**: - 1.1 The grade and chemical composition shall comply with Table 1. - 1.2 The deviation of the chemical composition of finished steel products shall comply with GB/T 222. 2. **Surface Quality, Dimensions, Shape, and Permissible Deviations**: - 2.1 The surface quality, dimensions, and shape of hot-rolled plates shall comply with GB/T 4237. - 2.2 The surface quality, dimensions, and shape of cold-rolled plates and strips shall comply with GB/T 3280. - 2.3 The surface quality, dimensions, and shape of hot-rolled bars shall comply with GB/T 1220. - 2.4 The surface quality, dimensions, and shape of cold-rolled bars shall comply with GB/T 4226. 3. **Melting Method**: - Unless otherwise specified in the contract, antibacterial stainless steel is typically produced using initial steelmaking (water) and furnace refining processes. Alternatively, special melting methods such as vacuum induction or electroslag remelting may be used. 4. **Delivery Condition**: - Antibacterial stainless steel is typically delivered in a heat-treated or heat-treated and pickled condition. The heat-treatment process shall be specified in the contract. If not specified, it shall be delivered in a fast-cooled condition at 1010°C to 1150°C followed by air-cooling at 600°C to 750°C. The delivery condition may be specified in the contract according to requirements or delivered in other conditions. 5. **Mechanical Properties**: - The mechanical properties of antibacterial stainless steel plates, strips, and bars shall meet the requirements specified in Tables 2 and 3. If any sample fails to meet the requirements or breaks outside the gauge length, the test shall be repeated in accordance with GB/T 17505. - **Table 2**: Mechanical Properties of Antibacterial Stainless Steel Plates and Strips - **Table 3**: Mechanical Properties of Antibacterial
