Understanding SUS Material- Stainless Steel Supplier Teda
What is SUS Material?
SUS refers to the Japanese standard for stainless steel materials. It is denoted as “SUS” followed by a number, with each number indicating a specific type of stainless steel.
- “S” stands for steel.
- “U” indicates its use.
- “S” signifies stainless.
SUS304 Material
Definition
SUS304 is a Japanese designation for 304 stainless steel, which adheres to the American ASTM standard. It is equivalent to the Chinese grade 0Cr18Ni9. The high nickel content and austenitic structure at room temperature make it highly resistant to corrosion.

SUS304 Key Properties
- Corrosion Resistance: Higher than Cr13 stainless steel.
- Plasticity and Toughness: Excellent at low, room, and high temperatures.
- Cold Forming and Weldability: Well-suited for forming and welding applications.
SUS304 Material Strength and Characteristics
- Ultimate Tensile Strength (UTS): Maximum stress before breaking under tension.
- Yield Strength: Stress level where permanent deformation begins.
- Elongation: Ductility, measured as a percentage of the material’s original length.
- Hardness: Resistance to deformation, often measured in Rockwell hardness (HRB/HRC).
Understanding Stainless Steel Series (370 and 470)
300 and 400 Series
- 300 Series: Austenitic stainless steel, known for its corrosion resistance and non-magnetic properties.
- 400 Series: Martensitic stainless steel, recognized for hardness and wear resistance.
370 and 470 Grades
While 370 and 470 are not standard designations under AISI or ASTM, they may refer to custom stainless steel compositions with rare metal elements added for specialized properties.
