SS 304 Round Bar: One Grade, Several International Names
When purchasing stainless steel from suppliers in different countries, the same material may be identified through different designation systems.
Stainless Steel 304 is one of the most widely used austenitic stainless-steel grades. Depending on the country, standard or technical document, buyers may refer to it as:
- SS 304
- AISI 304
- Type 304 Stainless Steel
- UNS S30400
- EN 1.4301
- X5CrNi18-10
- SUS304
These names are important for international procurement because an enquiry from India may use “SS 304 Round Bar,” while a European customer may mention EN 1.4301 Round Bar or X5CrNi18-10 Round Bar.
The exact product standard, chemical composition, dimensions and certification should always be confirmed before supply.
Manan Steel & Metals supplies stainless steel and industrial metal products for customers requiring specific grades, sizes and quantities.

What Is SS 304 Round Bar?
SS 304 Round Bar is a solid cylindrical bar manufactured from Type 304 austenitic stainless steel.
It is commonly selected for industrial components because of its combination of:
- Corrosion resistance
- Fabrication suitability
- General-purpose strength
- Weldability
- Surface appearance
- Availability in different sizes and finishes
The material is frequently used in engineering, food-processing, chemical, architectural and general fabrication applications.
For buyers working with international drawings or purchase orders, AISI 304, UNS S30400, EN 1.4301 and SUS304 are important designation references.
International Names and Designations of SS 304
| Designation System | Common Designation |
|---|---|
| Commercial name | Stainless Steel 304 |
| Indian market name | SS 304 |
| AISI / ASTM | Type 304 |
| UNS | S30400 |
| EN Material Number | 1.4301 |
| EN Steel Name | X5CrNi18-10 |
| Japanese designation | SUS304 |
| Common short name | SS304 |
These designations help buyers communicate the intended grade when dealing with international suppliers.
For example:
SS 304 Round Bar = AISI 304 Round Bar = UNS S30400 Round Bar = EN 1.4301 Round Bar = X5CrNi18-10 Round Bar = SUS304 Round Bar
However, buyers should not rely only on the name. The applicable standard and test certificate should also be checked.
Chemical Composition of SS 304
Type 304 stainless steel contains chromium and nickel as its major alloying elements.
Typical chemical limits are shown below:
| 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 limits can vary according to the applicable standard, product specification and purchasing requirement.
For critical applications, the buyer should request a material test certificate and confirm that the chemical composition complies with the required specification.
Important Characteristics of SS 304 Round Bar
1. General Corrosion Resistance
SS 304 offers useful corrosion resistance in many atmospheric and industrial environments. It is widely used where a general-purpose stainless-steel grade is required.
The actual corrosion performance depends on the environment, concentration of chemicals, temperature, surface condition and cleaning conditions.
