Material Science Essentials
Elemental Composition
Chromium (16–18%): Forms passive film against oxidation in dry/urban atmospheres.
Manganese (5.5–7.5%): Replaces partial nickel content to stabilize austenite structure.
Copper (1.5–2.5%): Enhances cold-working properties for deep-drawn components.
Low Carbon (≤0.15%): Balances weldability with intergranular corrosion resistance.
Processing Excellence
Bright Annealed (BA) Finish: Achieves 80–85% reflectivity for premium visual appeal.
No.3/No.4 Finish Options: Brushed surfaces with Ra 0.5–1.0μm for tactile aesthetics.
Precision Slitting: ±0.2mm width tolerance for automated fabrication lines.

Technical Guidance Hub
Q1: How does 201 perform in coastal areas?
A: Limited to 2–3 years outdoors; recommend 316 for saltwater exposure.
Q2: Welding best practices?
A: Use ER309L filler for mixed 201/304 joints; post-weld cleaning mandatory.
Q3: Surface protection during transit?
A: VCI (Vapor Corrosion Inhibitor) paper wrapping per ASTM D3950.
Q4: Passivation requirements?
A: Optional nitric acid passivation (ASTM A967) for enhanced oxide layer.
Q5: Maximum service temperature?
A: 300°C continuous (avoid prolonged 450–800°C to prevent σ-phase).
