High-Performance Stainless Steel Coil | Trusted Foshan Factory Quality
Product Overview
Our stainless steel coil is engineered for excellence, offering unmatched durability and versatility for industrial, construction, and HVAC applications. Manufactured at our Foshan-based facility, these coils meet global standards (ASTM, AISI, JIS) and are available in grades 304, 316L, 430, and 410. Ideal for stainless steel tubing coil systems and stainless steel heating coil applications, our products combine corrosion resistance, thermal stability, and mechanical strength.

Performance Characteristics
1. Tensile & Bend Strength
- Tensile Strength: Measures the maximum stress a stainless steel coil can withstand before breaking. For example, Grade 316L achieves ≥485 MPa, ensuring reliability in high-pressure environments like chemical pipelines.
- Bend Strength: Our coils resist deformation under load, critical for forming stainless steel tubing coil systems without cracking. Grade 430 retains structural integrity even after repeated bending.
2. Corrosion Resistance
- Passive Layer: Chromium (≥10.5%) forms a self-repairing oxide layer, preventing rust in humid or acidic conditions.
- Mo-Enhanced Grades: 316L includes 2–3% molybdenum for superior resistance to chlorides (e.g., marine or HVAC stainless steel heating coil systems).
3. Weight Calculation
Use the formula:
Weight (kg) = Thickness (mm) × Width (m) × Length (m) × Density (7.93 g/cm³)
Example: A 1.5mm × 1219mm × 2000mm coil weighs ≈28.9 kg/m².
Understanding Stainless Steel Rusting
Despite its rust-resistant reputation, stainless steel coil can corrode under specific conditions:
- Surface Contamination: Iron particles from tools or environmental debris disrupt the passive layer.
- Chloride Exposure: Saltwater or industrial chemicals accelerate pitting in grades like 304 (use 316L instead).
- Intergranular Corrosion: Poor welding or prolonged heat (450–850°C) causes chromium carbide formation, reducing corrosion resistance.
Identification & Certification
- Grade Marking: ASTM/AISI standards (e.g., 304, 316L) are laser-etched or tagged for traceability.
- Certifications: ISO 9001, SGS, and BV ensure compliance with international quality benchmarks.
