Food-Grade 316L Stainless Steel Sheet
Corrosion-Resistant Pioneer Industrial Preferred Choice
316L, the low-carbon version of 316 stainless steel (C ≤ 0.03%), exhibits significantly superior pitting resistance in chloride environments compared to 304 stainless steel due to its molybdenum content (2-3%). Key features include:
- Exceptional Corrosion Resistance: Outstanding performance in corrosive media like seawater and organic acids, especially suitable for high-salinity environments
- Biocompatibility: FDA-certified for direct contact with food and pharmaceuticals
- Processing Friendliness: Excellent weldability without post-weld annealing
- High-Temperature Stability: Continuous service temperature up to 450°C

Performance Characteristics and Applications of 16L Stainless Steel Sheets
1. Performance Characteristics
1.1 Corrosion Resistance
The austenitic structure containing 2%-3% molybdenum gives it excellent resistance to pitting and crevice corrosion, especially in chloride environments, making it suitable for harsh conditions such as seawater and chemical media.
1.2 Low Carbon Design
Carbon content ≤0.03%, eliminating the need for annealing after welding to prevent intergranular corrosion, suitable for manufacturing thick-section welded components.
1.3 Mechanical Properties
Tensile strength ≥485MPa, elongation >40%, combining high strength with good toughness, and excellent cold and hot workability.
1.4 Heat Resistance
Stable strength at high temperatures, able to withstand high-temperature environments up to 870℃, suitable for high-temperature equipment such as heat exchangers.
2. Main Applications
2.1 Chemical and Petroleum Industries
Used in equipment such as reaction vessels, pipelines, and storage tanks, resistant to acid, alkali, and hydrogen sulfide corrosion, ensuring the safety of chemical production.
2.2 Marine Engineering
Widely used in ship components, seawater desalination equipment, etc., due to their resistance to chloride ion corrosion, extending the lifespan of marine facilities.
2.3 Food and Medical
Conforming to food-grade standards, used in the manufacture and processing of equipment and storage containers; medical devices such as implants rely on their biocompatibility.
2.4 Construction and Industry
Architectural decoration, pressure vessels, and mechanical structural components; custom-made complex components using laser cutting, bending, and other processes.
3. Processing Advantages

Frequently Asked Questions
Q1: Do you offer custom processing?
→ Supports laser engraving/special-shaped cutting with 3D-to-CAD conversion services.
Q2: Is surface rust normal?
→ Not a material defect. Usually caused by iron dust contamination, removable with 10% nitric acid cleaning.
Q3: What distinguishes 316L from 316 stainless steel?
A: The “L” suffix indicates low carbon content (≤0.03%), which reduces carbide precipitation during welding and minimizes intergranular corrosion risk.
Q4: Can 316L be used in high-temperature environments?
A: Yes, it exhibits good oxidation resistance up to 800°C (1472°F) and retains strength at elevated temperatures due to its austenitic structure.
Q5: How to maintain 316L’s corrosion resistance?
A: Avoid prolonged exposure to high-chloride environments (e.g., undiluted seawater) without protective coatings. Regular cleaning removes contaminants that could compromise the passive layer.
