Advantages of SUS304 Hot Rolled Stainless Steel Plate Compared with Other Stainless Steel Plates
| Grade | Main Advantages | Limitations | Typical Applications |
|---|---|---|---|
| 304 / SUS304 | Excellent balance of corrosion resistance, strength, weldability, and cost-effectiveness | Not recommended for highly concentrated chloride environments | Vessel maintenance, construction, food processing, pressure vessels |
| 201 Stainless Steel | Lower cost, higher manganese content | Lower corrosion resistance and durability than 304 | Decorative panels, indoor applications, furniture |
| 316 / 316L Stainless Steel | Superior resistance to chlorides and seawater due to molybdenum addition | Higher material cost | Marine engineering, offshore platforms, chemical processing |
| 430 Stainless Steel | Good oxidation resistance and lower price | Ferritic structure with poor weldability and corrosion resistance | Household appliances, interior decoration |
| 321 Stainless Steel | Titanium stabilized for excellent high-temperature performance | More expensive than 304 | Exhaust systems, heat exchangers, aerospace components |
| 310S Stainless Steel | Outstanding heat resistance up to 1100°C | Higher cost and not necessary for general corrosion environments | Furnaces, boilers, heat treatment equipment |

Frequently Asked Questions (FAQ)
1. What is IMPA Code 671604?
IMPA Code 671604 is an international marine purchasing code used to identify SUS304 hot rolled stainless steel plates supplied for vessel maintenance and ship repair applications.
2. What standard does this stainless steel plate comply with?
The plate is manufactured according to ASTM A240 and can also comply with JIS G4304 and EN 10088 standards upon request.
3. What surface finish does this product have?
This product features a No.1 Finish, which is the standard surface finish for hot rolled stainless steel plates after annealing and pickling.
4. What is the difference between No.1 Finish and 2B Finish?
No.1 Finish is produced by hot rolling, annealing, and pickling, making it suitable for heavy industrial applications. A 2B Finish is produced from cold rolled material and provides a smoother, brighter surface for precision fabrication and decorative uses.
5. Is SUS304 suitable for marine environments?
SUS304 performs well in general marine atmospheres and ship maintenance applications. However, for continuous exposure to seawater or chloride-rich environments, 316 or 316L stainless steel is generally recommended because of its enhanced pitting and crevice corrosion resistance.
6. Can the plate be cut to custom sizes?
Yes. We provide cutting, shearing, laser cutting, plasma cutting, and other processing services according to customer drawings or specifications.
7. What thicknesses are available?
Hot rolled SUS304 stainless steel plates are commonly available from 3 mm to 100 mm, with customized dimensions available depending on project requirements.
8. Do you provide Material Test Certificates?
Yes. EN 10204 3.1 Material Test Certificates (MTC), PMI reports, and third-party inspections from SGS, BV, TUV, or other agencies can be provided upon request.
9. Why choose your company as a supplier?
Over 15 years of 304 stainless steel plate suppliers and export experience.
Compliance with ASTM, EN, JIS, and other international standards.
Large inventory with fast delivery.
