Welcome to Wuxi Yansheng Technology Co., Ltd. – a trusted manufacturer since 2017, with a factory spanning 1,000–3,000 square meters and an annual export value exceeding US$50 million. Our Hot Rolled ASTM 316L Pickled Surface Seawater Engineering Stainless Steel Plate is engineered to withstand the harshest marine environments, offering superior corrosion resistance and long-term durability. This product is specifically designed for seawater engineering projects where reliability under extreme conditions is non-negotiable.
Product Overview
Our stainless steel plate is manufactured from premium-grade 316L stainless steel, hot-rolled to achieve optimal mechanical properties, and then pickled to remove scale and impurities, resulting in a clean, uniform surface. The low carbon content of 316L minimizes carbide precipitation during welding, ensuring excellent weldability and resistance to intergranular corrosion. This makes it an ideal choice for seawater applications, desalination plants, offshore platforms, and chemical processing equipment.
Key Features & Technical Specifications
- Material Grade: ASTM 316L (UNS S31603) – contains molybdenum for enhanced pitting and crevice corrosion resistance in chloride environments.
- Surface Finish: Pickled (2D or 2B equivalent) – smooth, matte appearance, free from oxide scale, ready for further fabrication or direct use.
- Processing Method: Hot rolled – ensures consistent grain structure, high strength, and excellent formability.
- Dimensional Flexibility: Customizable thickness (3–100 mm), width (1000–3000 mm), and length (2000–12000 mm) to meet project-specific requirements.
- Standards Compliance: Conforms to ASTM A240/A480 standards, ensuring mechanical properties and chemical composition are strictly controlled.
- Applications: Seawater pipelines, heat exchangers, coastal infrastructures, shipbuilding, and chemical tanks.

Advantages for Your Business
- Corrosion Resistance: The addition of molybdenum provides exceptional resistance to chloride-induced stress corrosion cracking, pitting, and crevice corrosion – critical for seawater engineering.
- Weldability: Low carbon content reduces the risk of sensitization during welding, maintaining corrosion resistance in heat-affected zones.
- Cost-Efficiency: Hot-rolled pickled surface eliminates the need for additional surface preparation, saving time and processing costs.
- Customization: Our in-house cutting and processing capabilities allow us to supply plates in custom sizes, reducing waste and fit-up time on site.
- Reliable Supply: With a factory size of 1,000–3,000 m² and a dedicated team of 101–200 employees, we ensure consistent quality and on-time delivery.

Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ typically starts at 1 ton, but we can accommodate smaller quantities for sample orders or special projects. Please contact us for details. -
Q: What is the lead time for standard sizes?
A: For standard thicknesses and sizes, lead time is approximately 15–20 days after order confirmation. Custom sizes may require 25–30 days. -
Q: Can you provide cutting services (laser, plasma, or waterjet)?
A: Yes, we offer various cutting services to meet your exact dimensions. Additional charges may apply based on complexity. -
Q: Is the pickled surface suitable for painting or coating?
A: The pickled surface is clean and free of scale, providing an excellent substrate for painting or coating. However, we recommend a surface preparation test for your specific coating system. -
Q: Does this plate meet NACE MR0175/ISO 15156 for sour service?
A: While 316L is generally suitable for sour service environments, we can provide material with additional testing (e.g., hardness, SSC) upon request to meet specific standards. Please confirm your requirements. -
Q: What certifications can you provide with the shipment?
A: We can provide Mill Test Certificates (MTC) per EN 10204 Type 3.1, as well as certification for ISO9001, HACCP, and other relevant standards. Third-party inspection is also available. -
Q: How do you ensure the plate is suitable for seawater engineering?
A: Our 316L plates are manufactured with strict control of chemical composition and mechanical properties. The low carbon and molybdenum content ensure high resistance to chloride attack, making them ideal for continuous seawater exposure. -
Q: Can you supply plates with a 2B finish instead of pickled?
A: Yes, we offer both pickled (2D) and bright annealed (2B) finishes. Please specify your preference when ordering.
