SS304 / SS304L Stainless Steel Round Bar Supplier — Cut to Size & Full Length
E Steel Sdn Bhd supplies SS304 / SS304L stainless steel round bars 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 supply full length or cut to size with no minimum order quantity (MOQ), supported by EN 10204 3.1 Mill Test Certificates on every order.
What is SS304/SS304L Stainless Steel ?
SUS304 is the standard “18/8” stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Stainless Steel Grade 304 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans.For these applications it is common to use special “304DDQ” (Deep Drawing Quality) variants. Type 304 Stainless Steel is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. Grade 304 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.
Grade 304L, the low carbon version of 304, does not require post-weld annealing and so is extensively used in heavy gauge components (over about 6mm). Grade 304H with its higher carbon content finds application at elevated temperatures. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.
International Equivalent Material Standards
SS304 and SS304L are manufactured and traded under different designations depending on the country of origin.The table below lists the equivalent grades by international standard — useful for cross-referencing material certificates from Japan, Europe, China, or Korea.

SUS304 / SUS304L Corrosion Resistance
SS304 provides excellent corrosion resistance across a wide range of atmospheric and chemical environments.
It performs well against oxidising acids such as nitric acid and is resistant to most organic acids, food products, and mildly corrosive chemicals. It is widely used in food and beverage processing precisely because it does not impart taste, odour, or contamination.
Limitations to be aware of: SS304 is susceptible to pitting and crevice corrosion in warm chloride-containing environments, and to stress corrosion cracking (SCC) above approximately 60°C when exposed to chlorides.
In coastal Malaysia, Singapore, or Indonesian industrial zones with high chloride exposure, consider upgrading to SS316 / SS316L (EN 1.4401 / 1.4404) for critical applications.
Chloride resistance guideline:
- Up to ~200 mg/L chlorides at ambient temperature: SS304 is generally acceptable
- Up to ~150 mg/L chlorides at 60°C: SS304 may still be used with monitoring
- Above these thresholds or in submerged / marine environments: specify SS316L or duplex grades
Corrosion Resistance of SS304/SS304L Stainless Steel in Malaysia & Singapore Environments
In the tropical industrial environments of Peninsular Malaysia, Johor, and Singapore — where humidity, coastal air, and industrial chloride exposure are common — selecting the correct stainless steel grade is critical. SS304 performs reliably in: - Indoor food processing and pharmaceutical facilities - Air-conditioned architectural applications - Chemical handling with non-chloride media - Fresh water systems and structural components For coastal zones, marine structures, or applications in Singapore's Jurong Island petrochemical corridor, we recommend upgrading to SS316 / SS316L (1.4401 / 1.4404) which contains 2–3% molybdenum for significantly improved chloride pitting resistance. Contact our technical team for a grade selection consultation at no charge.
Heat Resistance & High Temperature Applications
Good oxidation resistance in intermittent service to 870°C and in continuous service to 925°C. Continuous use of SUS304 in the 425-860°C range is not recommended if subsequent aqueous corrosion resistance is important. SUS304L is more resistant to carbide precipitation and can be heated into the above temperature range.
SUS 304H has higher strength at elevated temperatures so is often used for structural and pressure-containing applications at temperatures above about 500°C and up to about 800°C. SUS304H will become sensitised in the temperature range of 425-860°C; this is not a problem for high temperature applications, but will result in reduced aqueous corrosion resistance.
Dual Certification for SUS304 / SUS304L
It is common for SS304 and SS304L to be stocked in “Dual Certified” form, particularly in plate and pipe. These items have chemical and mechanical properties complying with both SS304 and SS304L specifications. Such dual certified product does not meet SS304H specifications and may be unacceptable for high temperature applications.

Frequently Asked Questions (FAQ)
Q : What is the difference between SS304 and SS304L?
The primary difference is carbon content. SS304 allows up to 0.08% carbon, while SS304L is restricted to a maximum of 0.030% carbon. This makes SS304L more suitable for welded applications where sensitisation (chromium carbide precipitation) must be avoided without post-weld heat treatment. Both grades share the same minimum mechanical properties at room temperature, though SS304 has a marginally higher tensile strength ceiling.Q : What is 18/8 Stainless Steel ?
18/8 stainless steel is the common trade name for SS304.
The name refers to its nominal composition of 18% chromium and 8% nickel. It is the same material as SS304, SUS304, AISI 304, UNS S30400, and DIN 1.4301.
Q : Do you supply SS304/304L round bars with no minimum order quantity?
Yes. E Steel supplies SS304 and SS304L round bars with no minimum order quantity (MOQ). You may order a single piece or a full truck load. This is particularly useful for prototype fabrication, maintenance requirements, or low-volume production runs.Q : What is DIN / European equivalent of SS304 ?
The European EN / DIN equivalent of SS304 is 1.4301 (material number), also written as X5CrNi18-10. For SS304L, the equivalent is 1.4307 (X2CrNi19-11). Mill certificates from European mills will carry these designations instead of ''SS304.''
Q : Can you supply material with a Mill Test Report (MTR)?
Yes. Material Test Reports to EN 10204 3.1 (third-party witnessed). Heat number traceability is maintained throughout.Please specify your certification requirement when placing an enquiry.
Q : Is SS304 or SS316 more suitable for marine environments in Southeast Asia?
In coastal or marine environments common to Singapore, the Riau Islands, and coastal Peninsular Malaysia, SS316 / SS316L (containing 2–3% molybdenum) provides significantly better pitting and crevice corrosion resistance in chloride-rich environments. SS304 is generally suitable for indoor industrial and food-grade applications with controlled chloride exposure. For outdoor or submerged marine applications, we recommend upgrading to SS316L or consulting our technical team.Q : What sizes of SS304/304L round bars are available in Malaysia?
E Steel stocks SS304/SS304L round bars up to 450mm diameter in our Klang, Selangor warehouse. Standard lengths are 3 m to 6 m. Cut-to-length service is available. Non-standard diameters may be sourced on request with short lead times through our global procurement network.Q : What is the price of SS304/SS304L Stainless Steel Round Bars ?
