316 Stainless Steel Plate: Strength and Corrosion Resistance for Every Industry

Stainless steel is one of the most dependable materials across industries. Its strength, corrosion resistance, and aesthetic appeal make it suitable for countless applications. Out of all stainless steel grades, 316 stainless steel plate is among the most trusted options because of its ability to resist harsh environments, including saltwater, strong chemicals, and high temperatures.

If you are looking for a material that offers durability, versatility, and long-term performance, the SS 316 plate is an excellent choice. This blog explores the properties, benefits, manufacturing, types, and applications of 316 stainless steel plate in detail.

What is 316 Stainless Steel Plate?

A 316 stainless steel plate is a flat-rolled product of austenitic stainless steel containing chromium, nickel, and molybdenum. The addition of 2–3% molybdenum makes it superior to 304 stainless steel in terms of corrosion resistance, particularly in chloride-rich and acidic environments.

This grade is widely known for:

• High resistance to pitting and crevice corrosion

• Excellent mechanical properties

• Ability to withstand both low and high temperatures

• Hygienic and easy-to-clean surface

Because of these qualities, 316 SS plate is widely used in marine, chemical, and medical industries where standard stainless steel grades may not perform as well.

Chemical Composition of 316 Stainless Steel Plate

The properties of 316 stainless steel are a result of its balanced chemical composition:

• Chromium (16–18%) – Provides corrosion resistance

• Nickel (10–14%) – Increases toughness and ductility

• Molybdenum (2–3%) – Improves resistance to chlorides and harsh chemicals

• Carbon (≤0.08%) – Prevents carbide precipitation and maintains weldability

• Manganese (≤2%) – Enhances hot-working strength

• Silicon (≤1%) – Improves oxidation resistance

• Iron (Balance) – Base structure providing overall strength

This composition ensures superior performance in demanding environments.

Mechanical Properties of 316 Stainless Steel Plate

316 stainless steel plate offers strength, ductility, and toughness for multiple applications.

• Tensile Strength: 515 MPa minimum

• Yield Strength: 205 MPa minimum

• Elongation: 40% minimum

• Hardness: 217 HB maximum

• Density: 8.0 g/cm³

These mechanical properties make SS 316 plate suitable for structural as well as pressure-containing applications.

Key Features of 316 Stainless Steel Plate

1. Superior Corrosion Resistance
   The molybdenum content provides better protection against chlorides and acids compared to 304 stainless steel.

2. High Temperature Performance
   Performs well in continuous service up to 870°C and intermittent service up to 925°C.

3. Excellent Fabrication and Weldability
   Can be easily fabricated into different shapes and welded without losing properties.

4. Hygienic Surface
   Smooth and non-porous surface prevents bacterial growth, making it ideal for food and pharma sectors.

5. Non-Magnetic
   Remains non-magnetic in its annealed condition but may become slightly magnetic after cold working.

6. Aesthetic Appearance
   Polished finishes make it suitable for both industrial and decorative purposes.

Types of 316 Stainless Steel Plates

There are several variations of 316 stainless steel plate, each designed for specific industrial requirements:

• 316L Stainless Steel Plate

  • Low carbon version

  • Prevents carbide precipitation during welding

  • Common in chemical and pharmaceutical industries

• 316H Stainless Steel Plate

  • High carbon version

  • Provides higher strength at elevated temperatures

  • Used in furnaces, boilers, and heat exchangers

• 316Ti Stainless Steel Plate

  • Titanium stabilized

  • Resistant to sensitization during prolonged heating

  • Suitable for high-temperature service

These sub-grades expand the versatility of 316 stainless steel plate across industries.

Difference Between 304 and 316 Stainless Steel Plate

Both 304 and 316 belong to the austenitic stainless steel family, but their performance differs significantly.

• 304 Stainless Steel Plate

  • No molybdenum content

  • Suitable for general applications

  • More affordable

• 316 Stainless Steel Plate

  • Contains 2–3% molybdenum

  • Better chloride and acid resistance

  • Preferred for marine and chemical use

If long-term performance and resistance to aggressive conditions are priorities, 316 is the better investment.
