Grade 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.

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
