SS 304 Sheet: One Stainless Steel Grade, Multiple International Names
When stainless steel is purchased internationally, the same grade can appear under different designation systems.
A buyer in India may ask for SS 304 Sheet, while a European customer may specify EN 1.4301 Sheet or X5CrNi18-10 Sheet. An American specification may refer to Type 304 or UNS S30400, while a Japanese enquiry may use SUS304.
These designations are important for industrial procurement because identifying the material correctly is the first step toward matching a drawing, purchase order and material certificate.
For this reason, understanding the international names of Stainless Steel 304 Sheet can make communication between buyers, engineers and suppliers much easier.
ASTM A240/A240M is the relevant ASTM specification family for chromium, chromium-nickel and chromium-manganese-nickel stainless-steel plate, sheet and strip for pressure-vessel and general applications. The current active edition listed by ASTM is A240/A240M-26.

What Is SS 304 Sheet?
SS 304 Sheet is a flat stainless-steel product manufactured from Type 304 austenitic stainless steel.
It is one of the most widely specified stainless-steel materials for general industrial fabrication because it combines useful corrosion resistance, fabrication characteristics and austenitic stainless-steel properties.
SS 304 Sheet is used in applications where a flat stainless-steel material is required for fabrication, covering, equipment construction, enclosures, vessels, machinery and other engineered components.
Depending on the application, the material may be processed through:
- Cutting
- Bending
- Forming
- Drilling
- Punching
- Welding
- Laser cutting
- Plasma cutting
- Machining
The exact processing method should be selected according to the sheet thickness, component geometry, equipment and engineering requirements.
International Designations of Stainless Steel 304
Understanding the different names of the material can be particularly useful for export-oriented purchasing.
| Designation System | Common Designation |
|---|---|
| Commercial name | Stainless Steel 304 |
| Indian market | SS 304 |
| AISI / ASTM | Type 304 |
| UNS | S30400 |
| EN Material Number | 1.4301 |
| EN Steel Name | X5CrNi18-10 |
| Japanese designation | SUS304 |
| Common short form | SS304 |
| Commercial product name | 304 Stainless Steel Sheet |
The key names to remember:
SS 304 = AISI 304 = Type 304 = UNS S30400 = EN 1.4301 = X5CrNi18-10 = SUS304
However, these names should not replace the complete purchase specification.
When buying material for a critical application, the buyer should confirm the applicable product standard, dimensions, surface finish, testing and certification requirements.
Chemical Composition of SS 304 Sheet
The commonly specified chemistry for Type 304 stainless steel includes chromium and nickel as major alloying elements.
A typical composition is:
| Element | Typical / Maximum Requirement |
|---|---|
| Carbon | Up to 0.08% |
| Manganese | Up to 2.00% |
| Silicon | Up to 1.00% |
| Chromium | 18.00–20.00% |
| Nickel | 8.00–10.50% |
| Phosphorus | Up to 0.045% |
| Sulfur | Up to 0.030% |
| Nitrogen | Up to 0.10% |
The exact chemistry should always be checked against the applicable material specification and the purchaser’s requirements.
For material intended for a specific engineering application, the supplier’s material test certificate should be checked against the applicable specification.
Characteristics of SS 304 Sheet
Austenitic Stainless Steel
SS 304 belongs to the austenitic stainless-steel family.
Its combination of chromium and nickel contributes to its corrosion-resistant and fabrication characteristics.
General Corrosion Resistance
SS 304 provides useful corrosion resistance in many atmospheric and industrial environments.
Its actual performance depends on factors such as:
- Chemical concentration
- Temperature
- Exposure duration
- Surface condition
- Contaminants
- Cleaning procedures
Therefore, the application environment should always be considered before material selection.
Fabrication Suitability
SS 304 Sheet is widely used for fabricated components requiring cutting, bending, forming and welding.
Surface Appearance
Stainless-steel sheet is available in different surface finishes depending on the required appearance and application.
The required finish should therefore be specified in the purchase enquiry rather than assumed.
Industrial Applications of SS 304 Sheet
304 Stainless Steel Sheet is used in a wide variety of industrial and commercial applications.
Typical applications include:
- Industrial equipment
- Food-processing equipment
- Kitchen equipment
- Pharmaceutical equipment
- Chemical-processing equipment
- Storage equipment
- Machinery covers
- Equipment enclosures
- Architectural fabrication
- Industrial tanks
- Fabricated panels
- Machinery components
- Process equipment
- General engineering structures
- Interior and exterior fabrication
ASTM A240/A240M covers stainless-steel plate, sheet and strip for general applications as well as pressure-vessel applications, with chemical and mechanical requirements specified by the standard.
The suitability of SS 304 should nevertheless be assessed against the actual operating environment and design requirements.
Why Choose SS 304 Sheet?
1. Widely Recognized International Grade
SS 304 has multiple internationally recognized designation names.
This makes it easier for engineering and purchasing teams to communicate the intended grade across borders.
2. Useful Corrosion Resistance
The chromium-containing stainless-steel chemistry provides corrosion resistance suitable for many common industrial environments.
3. Fabrication-Friendly Product Form
Sheet form is practical for:
- Cutting
- Bending
- Forming
- Welding
- Fabricating
4. Suitable for General Industrial Applications
The material is used across equipment manufacturing, fabrication, food-related equipment and general engineering.
5. Multiple Specification Options
Buyers can define their requirement according to:
- Thickness
- Width
- Length
- Finish
- Edge condition
- Surface requirements
- Applicable standard
- Testing
- Certification
This allows the material to be specified more precisely for the intended application.

SS 304 Sheet for Export and International Enquiries
International customers may not always use the phrase “SS 304 Sheet.”
A European buyer may search for:
EN 1.4301 Stainless Steel Sheet
Another customer may use:
X5CrNi18-10 Sheet
An American buyer may specify:
UNS S30400 Sheet
A Japanese customer may write:
SUS304 Sheet
These different search terms can refer to the same commonly recognized Type 304 stainless-steel grade, but the exact standard and product requirements must still be confirmed before supply.
For an export enquiry, including the customer’s original designation in the purchase documentation can reduce confusion.
