Hemaokang Steel (Shandong) Co., Ltd., established in 2025, is a rising force in the global stainless steel industry with an annual export value between US$50 million and US$100 million. Our 316L stainless steel coil, precisely engineered at 2mm thickness and 1500mm width, offers an outstanding combination of corrosion resistance, formability, and mechanical strength. With an annealed condition and a controlled hardness of 80 HRB, this product is ideal for demanding applications in petrochemical, marine, and food processing environments. Backed by our ISO9001-certified quality management system and a dedicated team of 51–100 professionals, we deliver coils that meet the highest international standards.
Our 316L stainless steel coil is manufactured using advanced cold-rolling and annealing processes, ensuring consistent mechanical properties and a uniform surface finish. The 2mm thickness provides excellent rigidity while maintaining workability, and the 1500mm width reduces the number of welds required in large-scale fabrications. The 80 HRB hardness (Rockwell B scale) indicates a well-balanced ductility and strength, making it suitable for deep drawing, bending, and forming operations. The annealed condition eliminates internal stresses, improving corrosion resistance and weldability.
| Parameter | Value | Benefit |
|---|---|---|
| Grade | 316L (UNS S31603) | Low carbon content enhances weldability and reduces sensitization risk |
| Thickness | 2.0 mm ±0.05 mm | Consistent gauge for precise fabrication |
| Width | 1500 mm ±2 mm | Wide format reduces joint requirements |
| Hardness (HRB) | 80 ±5 | Balanced strength and ductility |
| Condition | Annealed | Stress-free, improved corrosion resistance |
| Surface Finish | 2B (Standard) | Smooth, reflective surface for aesthetic and functional applications |
| Standard Compliance | ASTM A240 / JIS G4305 | Globally recognized specifications |
Key Features and Advantages:
- Superior Corrosion Resistance – The molybdenum content in 316L provides exceptional resistance to chlorides, acids, and harsh chemicals, making it ideal for marine and chemical processing environments.
- Excellent Formability – With an annealed condition and 80 HRB hardness, the coil can be easily bent, stamped, or deep drawn without cracking or spring-back issues.
- Enhanced Weldability – Low carbon content (0.03% max) minimizes carbide precipitation during welding, preserving corrosion resistance in heat-affected zones.
- Precision Dimensions – Tight tolerances on thickness (±0.05mm) and width (±2mm) ensure consistent performance in automated production lines.
- Wide Width Advantage – 1500mm width reduces the number of seams and welds, lowering overall fabrication costs and improving structural integrity.
- Versatile Surface Finish – Standard 2B finish offers a bright, smooth surface suitable for both industrial and architectural applications.
- ISO9001 Quality Assurance – Every coil undergoes rigorous testing (chemical analysis, mechanical testing, surface inspection) to ensure compliance with international standards.
Typical Applications:
- Chemical and petrochemical equipment (tanks, heat exchangers, piping)
- Marine and offshore structures (platforms, shipbuilding, desalination plants)
- Food and beverage processing (storage tanks, conveyors, hygienic equipment)
- Pharmaceutical and biotechnology cleanrooms
- Architectural cladding, handrails, and decorative panels
- Automotive exhaust systems and components

Frequently Asked Questions
-
What is the difference between 316 and 316L stainless steel?
316L has a lower carbon content (max 0.03%) compared to 316 (max 0.08%). This reduces the risk of carbide precipitation during welding, making 316L more suitable for heavy-gauge welded structures. -
Can this coil be used for food contact applications?
Yes, 316L stainless steel is widely accepted in food processing due to its excellent corrosion resistance and non-reactive surface. It meets FDA and EU food contact regulations. -
What is the typical lead time?
For standard specifications (2mm, 1500mm, annealed, 2B finish), lead time is approximately 15–20 days after order confirmation. Custom sizes or finishes may require 25–30 days. -
Do you provide mill test certificates (MTC)?
Yes, we provide MTCs for every coil, including chemical composition and mechanical properties. Additional third-party inspection (e.g., SGS, BV) is available upon request. -
What packaging options are available?
We offer standard export packaging: inner waterproof paper, metal strapping, and outer wooden crates or steel pallets. Anti-rust coating can be applied for humid environments. -
Can you supply other thicknesses or widths?
Yes, we can produce coils from 0.3mm to 6.0mm thickness and widths from 600mm to 2000mm, subject to minimum order quantities. Please contact us for custom specifications. -
Is the coil suitable for deep drawing?
Yes, the annealed condition and 80 HRB hardness provide excellent ductility for deep drawing operations. We recommend testing with your specific tooling. -
What is the minimum order quantity (MOQ)?
For standard 2mm x 1500mm coils, MOQ is 5 tons per size. For non-standard sizes, MOQ may be higher. Please inquire for details.
