Here are 20 technical terms related to stainless steel, based on information from multiple authoritative sources:
1. SUS (Steel Use Stainless): The international abbreviation for stainless steel materials, widely used to identify stainless steel products in international trade.
2. 304/316L: Common grades of stainless steel materials, representing 18% and 16% chromium content respectively, and 8% and 10% nickel content, with excellent corrosion resistance.
3. Acid pickling: Surface treatment process for stainless steel, removing surface oxide scale and chromium compounds formed during welding to improve surface smoothness.
4. Polishing: Surface treatment process for stainless steel, using mechanical or chemical methods to make the surface smooth and shiny, enhancing the aesthetic appeal and corrosion resistance of the product.
5. Sandblasting: Surface treatment process for stainless steel, using high-pressure air to spray abrasive particles onto the surface, creating a uniform sandblasted effect, often used to enhance surface texture or remove surface dirt.
6. Electropolishing: An advanced surface treatment process for stainless steel, using electrolysis to remove surface oxide scale, achieving a smoother and brighter surface, and improving corrosion resistance.
7. Passivation: Surface treatment process for stainless steel, forming a dense oxide protective film through chemical methods, enhancing the corrosion resistance of stainless steel.
8. Drawing: Processing method for stainless steel, using mechanical or chemical methods to make the surface present a silk-like effect, enhancing the aesthetic appeal and feel of the product.
9. Embossing: Processing method for stainless steel, creating raised or recessed patterns on the surface, often used in the manufacturing of decorative stainless steel products.
10. Austenitic Stainless Steel: Mainly composed of austenitic stainless steel, with good corrosion resistance, plasticity, and toughness, being one of the most widely used types of stainless steel.
11. Ferritic Stainless Steel: With lower chromium content or no nickel addition, the structure is ferrite or ferrite + a small amount of austenite, with high resistance to stress corrosion.
12. Hot Rolling: Processing method for stainless steel materials, heating the steel billet to a high temperature and then rolling to form the desired shape and size.
13. Cold Rolling: Processing method for stainless steel materials, optimizing the mechanical properties and surface quality of the material through rolling at room temperature.
14. Cold Drawing: Processing method for stainless steel materials, pulling the steel material at room temperature to form the desired shape and size.
15. Welding: The process of firmly connecting two or more stainless steel materials through heat or pressure, widely used in the manufacturing and installation of stainless steel products.
16. Electroplating: Processing method using electrochemical principles to deposit a layer of metal or non-metal coating on the surface of stainless steel materials, to enhance their surface performance or appearance.
17. Dimension: The length, width, height, etc. of stainless steel products, which are important parameters for product quality and specifications.
18. Thickness: The thickness indicator of stainless steel products, which has a significant impact on the performance and service life of the product.
19. Tolerance: The allowable range of deviation between the dimensions and shapes of stainless steel products and their nominal values, which is an important indicator for quality control of the product.
20. Corrosion Resistance: The ability of stainless steel materials to resist corrosion by corrosive media, which is one of the important indicators for evaluating the performance of stainless steel.
These terms cover aspects such as the type of stainless steel material, surface treatment process, processing method, size specifications, and performance characteristics, and are the basis for understanding and applying stainless steel technology.
