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. is a specialist supplier of 304 and 304L stainless steel plates in Malaysia, supplying customers across Selangor, Kuala Lumpur, Johor, Penang, and Singapore.
We stock a wide range of thicknesses and dimensions, and offer precision bandsaw cutting to your exact size — 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. We supply them all.
304 stainless steel is the most widely used grade of austenitic stainless steel in the world.
It contains approximately 18% chromium and 8% nickel, giving it excellent corrosion resistance, good formability, and strong weldability.
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 must be avoided.
Both grades are sold and stocked as 304/304L dual-certified plates in most cases, meaning the material meets both specifications simultaneously.
Customers across Malaysia and Singapore often search using different material code systems depending on their industry standard or drawing requirement.
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 | — |
| ISO | X5CrNi18-10 | X2CrNi18-9 |
No matter which code is on your drawing, we can supply it.

Why Bandsaw Cut to Size Service for Stainless Steel 304/304L Plates
We operate multiple bandsaw cutting machines in our warehouse in Klang, Selangor.
Bandsaw cutting is the preferred method for cutting stainless steel plates because it delivers:
✅ Clean, burr-minimal cut surface — ready for machining or direct use
✅ Nicer cutting surface — no second process needed before CNC Machining
✅ No heat-affected zone — the material properties near the cut are preserved
✅ Efficient and fast — quick turnaround even for complex multi-piece cutting lists
✅ Ready Stock in Malaysia
No long lead times. Our 304/304L plates are in stock at our Klang warehouse, ready to cut and deliver.
✅ Serving Malaysia & Singapore + South Esia Markets.
We supply customers across Selangor, KL, Johor Bahru, Penang, and Singapore.
Twice a week to Singapore Markets.
✅ No Minimum Order Quantity (MOQ)
