Stainless Steel 201 vs 304: Which Grade for Your Sheet Metal Fabrication?
In sheet metal fabrication, 201 and 304 are the most widely used stainless steel grades. While similar in appearance, they have significant differences in core performance, processing adaptability, compliance, and cost. Choosing the wrong grade will directly affect product quality, service life, and bring compliance risks.
Core Differences at a Glance
1. Corrosion Resistance & Composition
2. Processing Adaptability
3. Cost & Compliance
Selection Guide
✅ Choose 201 for: Basic decorative parts in dry indoor environments, ordinary equipment housings, simple sheet metal parts without complex processes, short-term display props, low-budget projects without corrosion resistance or food-grade requirements.
✅ Choose 304 for: Sheet metal parts used outdoors, in humid/coastal high-salt spray environments, food/medical equipment accessories, precision bent and welded parts, export orders, and long-term load-bearing structural parts.
