304 vs 316 Chapas de Aço Inoxidável: Qual é a Mais Adequada para o Seu Projeto?

Selecting the correct stainless steel grade is critical for achieving long-term performance and cost efficiency. Among the various grades available, 304 e 316 stainless steel are the most widely used.

Understanding their differences helps architects, contractors, and manufacturers make informed decisions.

What Is 304 Aço Inoxidável?

304 stainless steel contains approximately 18% cromo e 8% níquel. It is known for:

• Excellent corrosion resistance
• Good formability
• Attractive appearance
• Cost effectiveness

It is commonly used in decorative panels, kitchen equipment, elevadores, and indoor architecture.

What Is 316 Aço Inoxidável?

316 stainless steel includes molybdenum, which significantly improves resistance to chlorides and harsh environments.

It is frequently used in:

• Coastal architecture
• Marine equipment
• Chemical facilities
• Outdoor installations
