• Grades: Austenitic (304, 316L, 321), Ferritic (430, 409), Duplex (2205, 2507).

• Chemical Composition Example (304): C ≤ 0.08%, Cr 18–20%, Ni 8–10.5%, Mn ≤ 2.0%, Si ≤ 1.0%.

• Thickness Range: 0.3–100 mm; Width: 1000–2500 mm.

• Mechanical Properties:

  • Tensile strength: 520–750 MPa

  • Yield strength: 205–450 MPa

  • Hardness: ≤ 200 HB (annealed)

  • Density: 7.93 g/cm³

• Surface Finishes: 2B, BA, No.4 brushed, No.8 mirror, patterned, etched.

• Corrosion Resistance: Salt spray resistance > 500 hours for 304; > 1000 hours for 316L in ASTM B117 test.

Applications & Advantages

• Applications: Food processing equipment, chemical storage tanks, marine structures, architectural facades, surgical instruments.

• Advantages:

  • Hygienic, non-porous surface

  • Long lifespan without need for protective coatings

  • Maintains strength and oxidation resistance at temperatures up to 870°C (316L)

  • Recyclable without loss of quality

• Example Case: 316L plates used in coastal building facades withstand chloride-induced corrosion for over 20 years without visible degradation.

Manufacturing Process & Standards

• Process:

  1. Melting in EAF → AOD refining → Continuous casting

  2. Hot rolling → Annealing → Pickling

  3. Cold rolling (if required) → Final annealing and pickling

  4. Surface finishing (polishing, coating, or texturing)

• Standards: ASTM A240, EN 10088-2, JIS G4304/G4305.

• Testing: PMI (Positive Material Identification), intergranular corrosion test (ASTM A262), mechanical property verification.

• Packaging: PVC film or paper interleaving between plates, strapped and palletized for shipping.
