The high chromium and nickel content provides excellent resistance to moisture, oxidation, chemicals, and many corrosive environments.
Bright polished surfaces are suitable for decorative hardware, furniture, architectural fittings, and precision engineering.
Cold drawn 304 stainless steel rods offer excellent dimensional accuracy and are easy to cut, drill, machine, and weld.
The material maintains excellent mechanical properties under both low and moderate temperature conditions.
Compared with carbon steel, 304 stainless steel offers significantly longer service life with minimal maintenance.
| Grade | Advantages | Limitations |
|---|---|---|
| 304 | Excellent corrosion resistance and cost-performance | Not suitable for strong chloride environments |
| 201 | Lower cost | Lower corrosion resistance |
| 303 | Better machinability | Reduced corrosion resistance due to sulfur addition |
| 316 | Better chloride resistance | Higher material cost |
| 430 | Magnetic and economical | Lower corrosion resistance |
