430 Stainless Steel Sheets
Stainless steel plate is a common metal material with the characteristics of corrosion resistance, high temperature resistance, high strength and aesthetics, which is widely used in industry, construction, home, medical and other fields.

Main characteristics of stainless steel plate
1.Corrosion resistance: containing chromium (Cr), nickel (Ni) and other alloying elements, the surface forms a dense oxide film (passivation layer), which can resist corrosion by water, acid, alkali and other media.
2.High strength: higher strength and hardness than ordinary carbon steel, suitable for load-bearing or wear-resistant scenes.
3.High/low temperature resistance: some models (e.g. 304, 316) can still maintain their performance at high or low temperatures.
4.Hygiene and environmental protection: non-toxic and odourless, easy to clean, suitable for food and medical industries.
5.Aesthetics: the surface can be polished, brushed, colour-plated, etc., commonly used in decorative fields.
Common materials (according to international standards)
| Material Model | Main Components | Feature | Typical Use |
| 201 | Cr-Mn-Ni | Low cost,weak corrosion resistance | Interior decoration, furniture |
| 304 | Cr18-Ni8 | General-purpose, acid and alkali resistant | Kitchen utensils, construction, industrial equipment |
| 316 | Cr16-Ni10-Mo2 | Resistant to seawater/chlorine corrosion | Marine engineering, chemical equipment |
| 430 | Cr17 (nickel-free) | Magnetic. Oxidation resistant | Household appliances, building decoration |
Surface treatment process
1.2B surface: bright annealed after cold rolling, smooth surface (most commonly used).
2.BA surface: mirror polishing, high reflectivity.
3.Brushed (HL): mechanical texture treatment, anti-fingerprint.
4.Sandblasted: matte texture, wear-resistant.
5.Titanium/copper plating: coloured surface, used for decoration.
Common specifications
1.Thickness: 0.3mm~80mm (Thin plate is commonly used for decoration, thick plate is used for industry).
2.Width: 1000mm, 1220mm, 1500mm, etc. (can be customised).
3.Length: 2000mm, 2438mm, 3000mm, etc.
Application fields
1.Building decoration: curtain wall, lift, doors and windows.
2.Industrial equipment: chemical tanks, pipes, mechanical parts.
3.home kitchenware: sinks, countertops, tableware.
4.Medical/food: surgical instruments, storage tanks, worktops.
5.Transportation: ships, car exhaust.
Purchasing considerations
1.Material selection: according to the environment (e.g. 316 is recommended for coastal areas).
2.Surface treatment: decorative use should focus on aesthetics, industrial use focus on wear resistance.
3.Certification standards: Check whether it meets the international/national standards such as ASTM, JIS, GB, etc.
