Q: Is SUS304 the same as SS304 and AISI 304?
They all refer to the same 18/8 austenitic stainless steel grade.
E Steel Sdn Bhd supplies SS304 / SS304L stainless steel plates from ready stock in Klang, Selangor to whole Malaysia and weekly truck to Singapore too.
Known internationally as SUS304 (JIS), AISI 304, UNS S30400, DIN 1.4301, and 18/8 stainless steel, Grade 304 is the most widely used austenitic stainless steel in the world.
We stock full plates in a wide range of thicknesses up to 150mm, and we don't only supply standard full plates but we offer precision bandsaw cut-to-size service too.
No minimum order required.
Whether you search for SS304, SUS304, AISI 304, EN 1.4301, DIN 1.4301, UNS S30400, or X5CrNi18-10 — they are all the same material family.
We supply them, along with the low-carbon 304L variant for welded and corrosion-critical applications.
304 is the most widely used austenitic stainless steel grade in the world — the standard "18/8" chromium-nickel alloy, offering an excellent balance of corrosion resistance, formability, weldability, and cost. It's the default choice across food processing, architectural, general fabrication, and light industrial applications wherever aggressive chloride exposure isn't a primary concern.
304L is the low-carbon variant (max 0.03% carbon vs 0.08% in standard 304), making it the preferred choice for welded components where sensitisation and intergranular corrosion at the heat-affected zone must be avoided. Both grades are commonly stocked and sold as 304/304L dual-certified plates, meaning the material meets both specifications simultaneously.
The table below covers all common equivalents:
| Standard | 304 Grade | 304L Grade |
|---|---|---|
| American (AISI / SAE) | AISI 304 / SS304 | AISI 304L / SS304L |
| Japanese (JIS) | SUS304 | SUS304L |
| European (EN) | EN 1.4301 | EN 1.4307 |
| German (DIN) | DIN 1.4301 | DIN 1.4307 |
| European Chemical Symbol | X5CrNi18-10 | X2CrNi18-9 |
| American UNS | UNS S30400 | UNS S30403 |
| Chinese (GB) | 06Cr19Ni10 | 022Cr19Ni10 |
| British (BS) | BS 304S31 | BS 304S11 |
We maintain ready stock of 304/304L stainless steel plates from established mills & origins.
Cut to size by cold cutting method (bandsaw cutting) is available too.

E Steel supplies both full plate and bandsaw cut-to-size, down to the exact dimensions on your cutting list from our ready stock inventory thicknesses up to 150mm.
We operate multiple bandsaw cutting machines at our Klang warehouse, dedicated to cold-cutting stainless steel plates. Bandsaw cutting is our preferred method which recommending to customers because it delivers:
A common question from customers: "Why not just plasma or laser cut my SS304 plate?"
Thermal cutting methods (plasma and laser) are fast for carbon steel, but for stainless steel and especially 304/304L used in food-grade, architectural, or precision fabrication applications — bandsaw (cold) cutting is generally the better choice.
| Factor | Bandsaw Cutting (Cold Cut) | Plasma / Laser Cutting (Thermal Cut) |
|---|---|---|
| Heat-Affected Zone (HAZ) | None — material stays cold throughout the cut | Present — heat can alter grain structure and corrosion resistance near the cut edge |
| Corrosion Resistance at Edge | Preserved — no sensitisation risk | Can be compromised, especially critical for 304L welded applications |
| Cut Surface Finish | Clean, straight, minimal burr | Dross, discoloration, oxide scale often present, needing secondary cleaning |
| Post-Processing Needed | Usually ready for CNC machining directly | Often requires grinding/deburring/passivation before use |
| Precision on Thick Plates | Consistent accuracy even at thk150mm | Heat distortion/warping risk increases with thickness |
| Suitability for Critical Industries | Preferred for food-grade, architectural, and precision fabrication | Higher risk of contamination or edge integrity issues for these industries |
| Cost for Small Quantities | Economical, no minimum order | Can be cost-effective for very thin sheet in high volume |
In short: Plasma and laser cutting introduce heat, which can create a heat-affected zone that compromises the very corrosion resistance customers choose stainless steel — and specifically 304/304L — for in the first place. Bandsaw cold-cutting avoids this entirely, which is why we recommend it as the default method for stainless steel plate, particularly for thicker sections and critical applications.
