Advantages
-
1. Strong corrosion resistance: it can resist the erosion of oxidizing, acid, salt and other corrosive media. 2. Good aesthetic surface smooth, bright, rich color, with a sense of modernity and fashion. 3. Easy processing: it can make parts of various shapes and sizes according to needs.
Introduction to different surface treatments of stainless steel
I. Rolling surface treatment (cold/hot rolling)2B: The most common cold rolling treatment process, through cold rolling, annealing, pickling and finally light rolling to obtain a smooth matte surface Medium reflectivity, suitable for building cladding and industrial equipment The surface roughness Ra value is about 0.1-0.5μm, which has both corrosion resistance and processing convenience2D: matte cold rolling treatment, less reflective than 2B, more uniform surface Suitable for industrial environments requiring low reflectivity, such as food processing equipment It is often used in engineering structural parts and metal jointsBA (bright annealing) : a highly reflective mirror surface formed by annealing in a controlled atmosphere with a surface roughness Ra<0.1μm Suitable for high-end decoration and electronic equipment casingNo.1 (fog surface) : after hot rolling, annealing, shot peening and pickling treatment, the surface is discontinuous granular Corrosion resistance is better than polished surface, mostly used in industrial containers2. mechanical polishing treatmentNo.3 (rough polishing) : use 100-120 mesh abrasive polishing, Ra 0.6-1.2μm Form visible linear lines, suitable for kitchen equipment and medical appliancesNo.4 (fine polishing) :150-180 mesh belt polishing, Ra 0.2-0.5μm Produces a uniform matte effect, commonly seen in elevator panels and building curtain wallsHL (hairline) : continuous unidirectional polishing to form fine parallel lines Both decorative and anti-fingerprint characteristics, mostly used in household appliances panelNo.8 (mirror) : Complete mirror effect with Ra<0.1μm is achieved by multi-stage polishing For high-end decoration and optical instruments


1. Raw material preparation and smeltingMaterial selection: mainly use stainless steel scrap, iron ore and alloying elements (such as chromium, nickel, molybdenum, etc.) to ensure that the chemical composition of the material meets the standard.Smelting: Heating raw materials to liquid form molten steel in an electric arc furnace (EAF). In this process, FeCr, Ni and other alloys may be added to adjust the composition.To refine: Decarbonization: Remove excess carbon and other impurities through AOD (argon oxygen decarbonization furnace) or VOD (vacuum oxygen decarbonization furnace) to improve the purity of molten steel.Secondary refining: The composition is further adjusted in LF (ladle refining furnace) to ensure the quality of molten steel.

2. Casting and primary processingContinuous casting (CC) : The continuous casting of refined molten steel into slabs or billets to form an initial solid shape.Billet heating: the continuous casting billet is heated to 1100 -- 1250℃ to facilitate subsequent rolling at a uniform temperature.

3. Rolling processHot rolling - descaling: The oxide layer on the surface of the billet is removed by high-pressure water. Rough rolling and finishing rolling: the heated blank is rolled through multiple passes and gradually thinned to the target thickness to form a hot rolling coil.Annealing: After hot rolling, the sheet is annealed (heated to a specific temperature and then cooled slowly) to eliminate internal stress and improve ductility.Pickling: use nitric acid-hydrofluoric acid mixture to remove the oxide scale produced by annealing, so that the surface is smooth and clean.Cold rolling: hot rolled pickling coils are further rolled at room temperature to obtain thinner (e.g. 0.3mm or less) cold rolled plates with higher flatness.

4. Surface treatment and post-processingPolishing/Drawing: Mechanical polishing or electrolytic polishing to improve surface finish, or drawing process to form texture.Slaying and molding: Cutting, bending, or welding the sheet into the final product shape as required. Plating/coating: some products need to be tinned, chromified or sprayed with anti-rust paint to enhance corrosion resistance.
