This article will focus on this topic and combine structured data to provide you with a detailed analysis of the characteristics, applications and market conditions of ST12 material.
1. Basic characteristics of ST12 material
ST12 is a common cold-rolled steel plate, which belongs to the low carbon steel category and is widely used in automobile manufacturing, home appliance casings, hardware accessories and other fields. The following are the main feature data of ST12:
| Project | parameters |
|---|---|
| Material standards | JIS G 3141 (Japanese Industrial Standard) |
| Carbon content | ≤0.10% |
| tensile strength | 270-410 MPa |
| Yield strength | ≥140 MPa |
| Elongation | ≥34% |
| Hardness | 40-75HRB |
2. Comparison between ST12 and similar materials
In recent hot discussions on the Internet, many users have compared ST12 with materials such as SPCC and DC01. The following is a performance comparison of three common cold-rolled steel plates:
| Material | Standard | Carbon content | Typical uses |
|---|---|---|---|
| ST12 | JIS G 3141 | ≤0.10% | Automobile inner panels, home appliance casings |
| SPCC | JIS G 3141 | ≤0.12% | General hardware |
| DC01 | EN 10130 | ≤0.12% | European standard general parts |
3. Market application hot spots of ST12
According to industry trends in the past 10 days, the demand for ST12 has increased significantly in the following areas:
1.New energy vehicle battery case: As the production of electric vehicles increases, ST12 has become the preferred material for battery casings due to its good formability and cost advantages.
2.Smart home appliance panel: Recently, many home appliance brands have released new products. The excellent surface quality of ST12 meets the appearance requirements of high-end home appliances.
3.Building decoration materials: At the recent building materials exhibition, orders for ST12 substrate color-coated boards increased by 15% year-on-year.
4. Precautions for processing ST12
According to the recent discussion hot spots in technical forums, special attention needs to be paid when processing ST12:
| Craftsmanship | Things to note |
|---|---|
| stamping | It is recommended that the mold gap be controlled at 8-12% of the material thickness |
| welding | CO2 gas shielded welding is preferred |
| surface treatment | Thorough degreasing is required before phosphating |
| storage | Humidity should be controlled below 60% |
5. Analysis of purchasing trends of ST12
Judging from recent e-commerce platform data, ST12 procurement shows the following characteristics:
1.Diversified specifications: 0.5-3.0mm thickness has the largest demand, accounting for 78% of the total transactions.
2.Increased surface requirements
3.Regional differences are obvious: East China’s procurement volume accounts for 43% of the country’s total, followed by South China (31%).
6. Future development prospects of ST12
Based on the recent discussions at industry summits, ST12 material will face the following development trends:
1.High performance: Developing ST12X series materials with higher strength level.
2.Environmental requirements: Chromium-free passivation treatment technology will become standard.
3.Intelligent production: The ST12 plate traceability system based on the Internet of Things is being piloted.
It can be seen from the above analysis that ST12, as a basic industrial material, still maintains an important market position under the current background of manufacturing upgrading.
