Description
JIS G3314 aluminized steel coil is the Japanese industrial standard for hot-dip aluminium coated steel sheets and coils. It defines the requirements for aluminium-coated steel used in heat-resistant equipment, automotive components, industrial machinery, and corrosion-resistant applications.
For international buyers working with Japanese engineering drawings or automotive supply chains, understanding JIS G3314 grade symbols, coating types, mechanical requirements, and certification requirements helps avoid specification mistakes.
What Is JIS G3314 Aluminized Steel?
JIS G3314 specifies hot-dip aluminium coated steel sheets and coils, known in Japanese as 熱浸アルミめっき鋼板. The standard focuses on steel products coated with aluminium to improve heat resistance, oxidation resistance, and corrosion protection.
Compared with ordinary galvanized steel, aluminized steel uses an aluminium-based coating that can form a stable aluminium oxide protective layer when exposed to elevated temperatures.
| Standard | Description |
|---|---|
| JIS G3314 | Hot-dip aluminium coated steel sheets and coils |
| Coating Method | Hot-dip aluminium coating |
| Main Properties | Heat resistance, oxidation resistance, corrosion protection |
JIS G3314 Grade Symbol Explained
The JIS G3314 grade system uses symbols to identify coating type and application characteristics. The main grades are SA1C and SA1D.
| Symbol | Meaning |
|---|---|
| S | Steel base material |
| A | Aluminium coating |
| 1 | Aluminium coating type classification |
| C/D | Application and performance category |
SA1C and SA1D: Two Main JIS G3314 Types
The biggest difference between SA1C and SA1D is the coating composition and intended application.
| Grade | Coating Type | Main Feature |
|---|---|---|
| SA1C | Aluminium-silicon coating | High-temperature oxidation resistance |
| SA1D | Aluminium coating | Corrosion protection and surface durability |
SA1C is commonly selected for heat-resistant components, while SA1D is used where aluminium coating corrosion protection is the main requirement.
JIS G3314 Grade Classification
JIS G3314 may include different quality levels depending on forming requirements and application needs.
| Grade | Application Focus | Typical Requirement |
|---|---|---|
| SA1C-1 | Heat-resistant components | Standard forming and thermal performance |
| SA1C-2 | More demanding forming parts | Improved processing requirements |
Mechanical Properties of JIS G3314 Aluminized Steel
Mechanical requirements depend on steel grade, thickness, and product category. Typical inspection focuses on tensile strength, yield behavior, elongation, and forming performance.
| Property | Inspection Purpose |
|---|---|
| Tensile Strength | Confirms structural performance |
| Yield Strength | Evaluates deformation resistance |
| Elongation | Determines forming capability |
| Coating Weight | Verifies aluminium protection level |
JIS G3314 Coating Weight Requirements
The coating weight requirement is an important quality factor because it directly influences heat resistance and service life.
| Inspection Item | Purpose |
|---|---|
| Coating Mass Measurement | Confirm aluminium coating quantity |
| Surface Inspection | Check coating defects |
| Adhesion Test | Confirm coating stability after forming |
JIS G3314 vs ASTM A463 vs EN Aluminized Steel
International projects often use different standards for similar aluminium coated steel products. Buyers should confirm equivalent grades before ordering.
| System | Standard | Common Classification |
|---|---|---|
| Japan | JIS G3314 | SA1C / SA1D |
| USA | ASTM A463 | Type 1 / Type 2 |
| Europe | EN 10346 | DX + AS grades |
