Pre-Seasoned Cast Iron Wok - Fast Heat & Durable

What is a Pre-Seasoned Cast Iron Wok? Product Overview and Core Features

A Pre-Seasoned Cast Iron Wok is a high-performance cooking vessel made from industrial-grade cast iron, treated during production with a layer of food-safe vegetable oil at high temperature, which polymerizes to create a protective, naturally non-stick surface. This process delivers exceptional durability, uniform heat distribution, and corrosion resistance.

Manufacture: Sand-casting, CNC finish machining, then pre-seasoning at 170-200°C using edible oil.
Certification: Conforms to ISO 9001 (quality management), ANSI/NSF (food safety), and FDA food-contact regulations.
Longevity: >10 years in heavy use, up to 20 years in moderate use settings.
Size Range: Usual diameters: 30cm, 36cm, 40cm, 45cm, 50cm; customizable on request.

Technical Advantages of Pre-Seasoned Cast Iron Wok

Uniform Heat Conductivity: Cast iron’s thermal mass (0.46 J/g/K) ensures minimal temperature drop and optimal browning, crucial in energy-saving commercial kitchens (energy efficiency up to 23% higher than aluminum).
Pre-Seasoned Surface: Instantly ready to use, saving 2 hours of manual seasoning per wok on average.
Corrosion Resistance: Passes 24-hr salt-spray test (per ASTM B117), outperforming typical carbon steel alternatives in acidic and high-humidity environments (industries: canteens, chemical, metallurgical kitchens).
Mechanical Strength: Tensile strength >200 MPa, drop tested from 1 meter.
Eco-friendly and Recyclable: Iron is 100% recyclable; no hazardous coatings.

FAQs: Advanced Knowledge on Pre-Seasoned Cast Iron Wok (Expert FAQ)

Q1: What is the difference between EN-GJL-250 and ASTM A48 Class 25 for cast iron?

A: Both are cast iron grades. EN-GJL-250 (as per ISO 185) has higher tensile strength (≥250 MPa) compared to ASTM A48 Class 25 (≥172 MPa), thus providing better resistance to deformation and fracture, especially for large-diameter woks under rigorous industrial use.

Q2: How does the pre-seasoned surface differ from traditional wok finishes?

A: A Pre-Seasoned Cast Iron Wok is oven-cured with edible oil, forming a food-safe polymerized layer (per ASTM D6400). This results in superior non-stick properties, eliminates the need for manual initial seasoning, and increases corrosion resistance compared to bare or enameled finishes.

Q3: What testing standards are used during inspection?

A: Products are batch-tested to ISO 9001 (quality), ANSI/NSF (food safety), and field mechanical properties are sampled as per EN1561 (European standard for grey iron). Corrosion testing follows ASTM B117 salt spray procedure, ensuring suitability in humid, food-contact environments.

Q4: What wall thickness is recommended and why?

A: 4–5 mm is the industry norm for commercial Pre-Seasoned Cast Iron Wok. This thickness offers optimal thermal mass for uniform heat distribution and minimizes risk of hot spots, cracks or breakage under sudden temperature shifts typical in high-power kitchens.

Q5: Can the wok be used on induction cookers?

A: Yes, cast iron is fully ferromagnetic, making the Pre-Seasoned Cast Iron Wok suitable for all heating sources: induction, gas, electric, and open fire.

Q6: What food safety certifications apply?

A: Essential certifications include ISO 9001 (quality system), FDA food-contact compliance (CFR 21), and ANSI/NSF standards for food-service equipment, as documented in supplier technical datasheets.

Q7: What maintenance is required to ensure maximum lifespan?

A: After use, rinse with hot water, avoid harsh detergent, and dry immediately. Apply a thin coat of edible oil post-cleaning. Do not soak or air-dry, as both can undermine even the polymerized pre-seasoning layer over the years.
