Characteristics |
SUS 301 |
- Contain lower Cr and Ni content than 304 does.
- Cold working increase strength and generates magnetism.
- Excellent corrosion resistance and strength at high temperature. |
SUS 304 |
- Most widely used, good mechanical properties and low carbon.
- Corrosion resistance.
- Good toughness at low temperature. |
SUS 304L |
- Low carbon.
- No heat treatment after welding.
- Strict corrosion resistance. |
SUS 316 |
- Excellent oxidation, heat, pitting and corrosion resistance. |
SUS 316L
SUS 316L
SUS 316L |
- Low carbon.
- Great granular corrosion resistance after heat treatment
- Stress removed after welding. |
SUS 430
SUS 430
SUS 430 |
- Great oxidation resistance.
- Cheap & good formability.
- Low thermal expansion coefficient. |

Surface Type |
Characteristics |
Thickness Range (mm) |
2B |
Products made through refined rolling of 2D to get higher brightness, flatness and improved mechanical properties. |
0.25 ~ 3.00 |
2D |
Products by cold-rolling, heat treatment and annealing and picklingor those having finished similar treatment. (with good deep drawing) |
0.25 ~ 3.00 |
BA |
Products made by cold-rolling, bright annealing and skinpass, have high reflesibility & luster |
0.25 ~ 2.00 |
HL |
Products have continuous abrasive pattern acquired by polishing on No.4 with an abraser of appropriate density. |
0.40 ~ 2.00 |
NO.4 |
Products grinded with abraser of 150~180Mesh, have more graceful silver gray surface. |
0.40 ~ 2.00 |
