Brand Hemaokang Steel

Hemaokang Steel (Shandong) Co., Ltd. proudly presents our premium 316L Stainless Steel Plate Cold Rolled with thickness ranging from 1mm to 20mm and a standard 2B surface finish. As a reliable supplier with ISO9001 certification and an annual export value of US$50-100 million, we ensure each plate delivers exceptional corrosion resistance, dimensional accuracy, and long-term durability. Whether you need sheets for chemical processing, marine equipment, or architectural cladding, our 316L cold rolled plates are engineered to meet the highest industry standards.

Our 316L stainless steel plates are produced through advanced cold rolling technology, which provides a smooth, bright 2B surface ideal for forming, welding, and polishing. The low carbon content (max 0.03%) of 316L significantly reduces the risk of intergranular corrosion, making it suitable for applications where welding is required. With thickness flexibility from 1mm to 20mm, we accommodate a wide range of project requirements, from light-duty panels to heavy structural components.

Key Features & Benefits

Superior Corrosion Resistance: 316L contains molybdenum, providing excellent resistance to chlorides, acids, and harsh chemicals – ideal for marine, chemical, and pharmaceutical environments.
2B Surface Finish: Cold rolled with bright annealing, the 2B surface offers a smooth, reflective appearance that is easy to clean and suitable for sanitary applications.
Wide Thickness Range: From 1mm to 20mm, we serve both thin-gauge projects (e.g., food processing equipment) and thick-plate needs (e.g., pressure vessels).
Excellent Weldability: Low carbon content minimizes carbide precipitation during welding, maintaining corrosion resistance in heat-affected zones.
Dimensional Accuracy: Strict tolerances (ASTM A240) ensure consistent flatness, squareness, and thickness – reducing waste during fabrication.
Customizable Sizes: Widths from 1000mm to 2000mm and lengths up to 6000mm are available; we also offer cutting, polishing, and edge processing services.

Length	2000mm, 2438mm, 3000mm, 6000mm (customizable)
Surface Finish	2B (cold rolled, bright annealed, Ra ≤ 0.5μm)
Standard	ASTM A240, JIS G4304, EN 10028-7
Chemical Composition (Typical)	C ≤0.03%, Si ≤1.00%, Mn ≤2.00%, P ≤0.045%, S ≤0.030%, Cr 16.0-18.0%, Ni 10.0-14.0%, Mo 2.0-3.0%

Our cold rolled plates undergo rigorous quality control from raw material inspection to final packaging. Each batch is tested for mechanical properties (yield strength ≥170 MPa, tensile strength ≥485 MPa, elongation ≥40%) and thickness tolerance. The 2B surface is achieved through a process of cold rolling, annealing, and pickling, resulting in a uniform matte finish that is both aesthetic and functional.

Applications

Chemical & petrochemical processing equipment (tanks, heat exchangers)
Marine and offshore structures (boat hulls, docks, seawater piping)
Food and pharmaceutical processing (sanitary surfaces, brewing vessels)
Architectural cladding, roofing, and interior design elements
Pressure vessels, boilers, and industrial machinery components

Frequently Asked Questions (FAQ)

Q: What is the difference between 316 and 316L stainless steel?
A: 316L has a lower carbon content (max 0.03%) compared to 316 (max 0.08%). This makes 316L more resistant to intergranular corrosion after welding, making it the preferred choice for welded structures.
Q: What does the 2B surface finish mean?
A: 2B is a cold rolled, bright annealed finish that is smooth, reflective, and free of defects. It is the most common finish for general industrial applications and provides an excellent base for further polishing or coating.
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 1 ton per size, but we can accommodate smaller orders for samples or urgent projects. Please contact our sales team for details.
Q: Can you provide customized sizes and cutting services?
A: Yes. We offer custom widths, lengths, and thicknesses within our production capabilities. We also provide laser cutting, shearing, edge trimming, and deburring services.
Q: How do you ensure the quality of the plates?
A: We follow ISO9001 procedures and perform in-house testing for chemical composition, mechanical properties, and dimensional accuracy. Certificates of compliance (MTC) are provided with each shipment.
Q: What packaging do you use for export?
A: Plates are packed in bundles with steel straps, waterproof paper, and plastic film. For sea freight, we use wooden crates or pallets to prevent damage during transit.
Q: What is the typical lead time?
A: For standard sizes in stock, delivery is 7-15 days after order. For custom orders, lead time is 15-30 days depending on quantity and complexity.
Q: Do you supply other surface finishes like BA or No.4?
A: Yes. In addition to 2B, we can supply BA (bright annealed), No.4 (brushed), and mirror (8K) finishes upon request. Please specify your requirements.
