SG295 Steel

Supplying SG295 hot-rolled steel coil to Vietnam's gas cylinder manufacturers. 100% compliant with JIS G3116 standard, with full Mill Test Certificate (MTC) traceability. We understand Vietnam's import regulations – including QCVN compliance and CR mark requirements – and ensure every shipment comes with complete documentation for smooth customs clearance.

SG295 is a high-strength steel grade specified under JIS G3116, the Japanese standard for steel sheets, plates, and strips used in welded gas cylinders (LPG, CNG, acetylene, and industrial gases). With minimum yield strength of 295 MPa and excellent weldability, it's the preferred material for cylinders up to 500 liters capacity.

Over the past decade, we've specialized in gas cylinder steels, supplying to manufacturers across Asia and specifically to Vietnam. We know that importing gas cylinder materials into Vietnam requires more than just good steel – it requires:

 Complete documentation for QCVN conformity assessment.

 Third-party inspection readiness (SGS, BV, etc.).

 Clear traceability for CR mark registration.

Key Takeaways：For Vietnamese gas cylinder manufacturers, SG295 is the most cost-effective grade under JIS G3116. While SG255 offers higher elongation (28% vs 26%), its lower tensile strength (≥400 MPa) fails the 1.5x burst pressure test for standard 12.5kg LPG cylinders. General structural steel like Q235B is strictly prohibited due to its unpredictable weld toughness under cyclic pressure. Always verify your Mill Test Certificate (MTC) shows JIS G3116 compliance – our SG295 coils provide guaranteed 310-340 MPa yield strength for a safe stamping process window.

Detailed description

 

What These Numbers Mean for Your Cylinder Production in Vietnam

 

JIS G3116 Full Compliance

All our SG295 coils are manufactured strictly according to JIS G3116:2020, with chemical composition and mechanical properties guaranteed. This forms the basis for QCVN conformity assessment in Vietnam

 

Full Traceability – MTC Provided with Every Shipment

Every coil comes with the original Mill Test Certificate (MTC) showing:

Heat number and chemical analysis

Mechanical test results (yield, tensile, elongation)

Conformity statement to JIS G3116

 

Third-Party Inspection – Fully Supported

We welcome and fully support pre-shipment inspection by any internationally recognized agency:

 SGS

 Bureau Veritas (BV)

 Intertek

 TÜV

Any agency your importer specifies

We'll coordinate sampling, testing, and documentation – making your QCVN conformity process smoother

 

HS Code Accuracy – Smooth Customs Clearance

Your SG295 coils will be classified under the correct HS code for Vietnam imports:

HS Code: 7208.3890 – Hot-rolled steel coils, pickled, of a thickness of 3-4.75mm (or as per your specific dimensions)
We ensure all commercial documents match this classification for seamless clearance.

User Evaluation

I have been cooperating with this supplier for three years, and what gives me the greatest peace of mind is that their documents are always error-free. The MTC (Material Certificate) for each batch of goods is sent along with the goods, with the furnace number and batch number clearly marked. The Pakistan Explosives Department (DOE) reviews it once and approves it. For the last urgent order, we placed the order on Friday and they sent us all the scanned copies on Monday, allowing us to prepare for customs clearance in advance. Such level of cooperation is not something that every supplier can achieve.

Ho Chi Minh, Vietnam · A certain LPG Gas Cylinder Manufacturing Factory

I have been using this SG295 steel for three years. The biggest impression I have is its excellent stability. Their yield strength remains stable between 310-340 MPa, neither too high nor too low - too high would cause cracking during stamping, and too low would fail to meet safety standards. This range is exactly the optimal process window for our equipment, and the workers can operate smoothly, with the yield rate remaining above 98%.

Their dimensional accuracy is also very stable. The width we used was 1240mm. The edges were neat and there was no wavy shape. After longitudinal shearing and strip cutting, there were fewer burrs at the edges, which reduced the subsequent processing steps. For us in the production field, the materials are convenient to handle, and this is the greatest support."

FAQ

 

 

01.Does your SG295 sheet material comply with the requirements of the Vietnamese QCVN technical regulations?

Our SG295 is strictly manufactured in accordance with the JIS G3116 standard and comes with complete MTC. These documents can serve as the technical basis for you to submit the Declaration of Conformity to the Vietnamese authorities. If your product needs to comply with QCVN mandatorily, we can provide all the necessary test reports and technical documents in coordination.

02.What is the corresponding Vietnam HS code for your SG295 sheet material?

According to the classification of Vietnam's customs, hot-rolled coil materials are usually classified under HS Code 7208.3890 (thickness 3 - 4.75mm) or related subheadings. We will provide you with accurate HS code suggestions based on your specific specifications to ensure a smooth customs clearance process.

03.If my Vietnamese clients require PSI testing, could you assist with it using SGS or BV?

Sure. We have long-term cooperation experience with international inspection agencies such as SGS and BV. We can fully cooperate in the inspection process, sample collection, and report issuance. Vietnam recognizes the inspection results of these international agencies and they can be directly used for your QCVN compliance assessment.

04.What is the minimum order quantity?

We support flexible ordering. For ready-made products, an order of 1 roll (approximately 3-8 tons) is required; for custom rolled products, an order of 20 tons is usually necessary (one furnace batch number). New customers are welcome to place a trial order first.

05.How long does it take to deliver to Ho Chi Minh City or Haiphong Port?

From the major Chinese ports (Shanghai, Tianjin) to Ho Chi Minh City or Haiphong Port, the sea transportation usually takes 7 to 10 days. We will arrange the fastest shipping schedule for you.
