Key Mechanical & Physical Properties
Tensile Strength
The tensile strength of 316 stainless steel sheets ranges between 515 MPa (75,000 psi) and 690 MPa (100,000 psi), depending on the temper and thickness. This high strength ensures resistance to deformation under load, making it suitable for structural applications like marine components and chemical tanks.
Bend Strength
316-grade sheets exhibit excellent bend strength, allowing them to withstand repeated flexing without cracking. For cold-rolled sheets, the minimum bend radius is approximately 1x thickness for annealed conditions and 2x thickness for hardened tempers.
Identification & Marking Methods
316 stainless steel sheets are identified using standardized codes:
- ASTM A240: UNS S31600
- EN 1.4401: X5CrNiMo17-12-2
- JIS SUS316
Sheets may also feature laser-etched or stamped markings indicating grade, thickness, and manufacturer certifications (e.g., ISO 9001).
Weight Calculation Formula
Calculate the weight of a stainless steel sheet using this formula:
Weight (kg) = Length (m) × Width (m) × Thickness (mm) × Density (7.99 g/cm³)
Example: A 2m × 1m × 3mm sheet weighs 2 × 1 × 3 × 7.99 = 47.94 kg.
Why Does Stainless Steel Corrode?
While stainless steel sheet 316 grade is highly corrosion-resistant, localized rusting may occur due to:
- Chloride Exposure: Prolonged contact with seawater or de-icing salts.
- Mechanical Damage: Scratches or gouges that compromise the passive oxide layer.
- Galvanic Corrosion: Contact with dissimilar metals in electrolyte-rich environments.
- Improper Cleaning: Residual contaminants (e.g., iron particles) accelerating oxidation.
Regular cleaning with pH-neutral solutions and avoiding abrasive tools minimizes these risks.
How to Cut Stainless Steel Sheet
Cutting stainless steel sheet requires precision to avoid work hardening and edge distortion. Popular methods include:
- Laser Cutting: Ideal for complex shapes and thin sheets (up to 25mm).
- Waterjet Cutting: Suitable for thick sheets (up to 150mm) without thermal distortion.
- Plasma Cutting: Cost-effective for mid-thickness sheets (3mm to 50mm).
- Shearing: Best for straight cuts on thin gauges (<6mm).
Always use lubricants to reduce heat and wear-resistant blades to maintain cut quality.
Applications of 316 Stainless Steel Sheets
- Marine Engineering: Boat fittings, offshore platforms.
- Medical Devices: Surgical instruments, MRI machines.
- Food Processing: Tanks, conveyor systems.
- Architecture: Cladding, handrails.
Frequently Asked Questions (FAQs)
Q1: Can 316 stainless steel be welded?
Yes, it is weldable using TIG or MIG methods. Post-weld annealing restores corrosion resistance.
Q2: Is 316 stainless steel magnetic?
It exhibits slight magnetism after cold working but is generally less magnetic than 430 or 304 grades.
Q3: What is the maximum operating temperature?
316 sheets withstand temperatures up to 870°C (1600°F) intermittently and 925°C (1700°F) in short bursts.
