The Ultimate Guide to Stainless Steel Plate: Choosing the Right Grade for Your Project

1. Understanding Stainless Steel Plate Grades

Selecting the correct grade is the most significant factor in determining the lifespan of your components. At Ruixiang, we categorize our plates based on their metallurgical structure and performance:

Austenitic Series (304, 304L, 316, 316L)

The most widely used "300 series" plates. Grade 304 is the industry standard for food processing and general decoration due to its excellent formability. For marine environments, Grade 316L is essential, as its molybdenum content resists chloride-induced pitting.

Duplex Steel (S31803, S32205)

For high-strength requirements, Duplex plates offer twice the strength of austenitic grades and superior resistance to stress corrosion cracking, making them ideal for the oil and gas industry.

2. Surface Finishes: Function Meets Aesthetics

The finish of a stainless steel plate defines its corrosion resistance and ease of cleaning. We offer a variety of standard and decorative finishes:

• No.1 (Hot Rolled): Annealed and pickled, used in industrial equipment where smoothness isn't a priority.
• 2B (Cold Rolled): A smooth, slightly reflective finish, the most common base for further polishing.
• 8K Mirror: Highly reflective, used in luxury architecture and ornamental projects.
• No.4 / Hairline: Brushed texture, perfect for elevators and kitchen appliances to hide fingerprints.
