Detailed comparison of stainless steel SUS303 and SUS304: characteristics, applications, advantages and disadvantages. Find out which type of steel is suitable for your industrial project.
When choosing materials for industrial projects, SUS303 stainless steel and SUS304 stainless steel are always the two top choices. This article will compare in detail to help you understand the differences, from machinability to corrosion resistance, to find the optimal solution for your needs.
Overview of Stainless Steel SUS303 and SUS304
| Criteria | Stainless Steel SUS303 | Stainless Steel SUS304 |
|---|---|---|
| Chemical composition | Contains Chromium (17-19%), Nickel (8-10%), and Sulfur (0.15-0.35%), which significantly improves machinability. | Composed of Chromium (18-20%), Nickel (8-10.5%), and low Carbon (≤0.08%), ensuring purity and durability. |
| Outstanding features | SUS303 stainless steel is famous for its easy machinability due to its Sulfur content, ideal for intricate details. | SUS304 stainless steel stands out with its superior corrosion resistance and high ductility, suitable for harsh environments. |
| Application | Suitable for manufacturing machine parts, bolts, nuts, and parts in the aviation industry thanks to its high precision. | Often used in food equipment, medical instruments, and architectural works due to its smooth surface and long-lasting durability. |
The table above shows that SUS303 stainless steel is the optimal choice for applications requiring precision machining, while SUS304 stainless steel is more suitable for projects requiring high corrosion resistance.
Stainless Steel SUS303 vs SUS304: Key Differences
| Criteria | Stainless Steel SUS303 | Stainless Steel SUS304 |
|---|---|---|
| Machinability | Easy to cut and drill due to its high Sulfur content, ideal for easy machining of stainless steel. | More difficult to machine, often requires specialized equipment, increasing production time and cost. |
| Corrosion resistance | Suitable for less corrosive environments, such as in internal machinery manufacturing. | Outstanding corrosion resistance in harsh environments (chemicals, seawater, humidity), making it an ideal choice for corrosion-resistant stainless steel. Suitable for construction contractors who need long-lasting materials. |
| Cost and efficiency | Lower price, save processing cost, suitable for small scale projects. Purchasing management often prioritizes to optimize budget. | Higher price but superior durability, low maintenance, suitable for long term projects. |
The above comparison table makes it easy to see that SUS303 stainless steel is suitable for projects that require fast machining, while SUS304 stainless steel is ideal for applications that require high strength and corrosion resistance.
