Electrolytic Chromium Coated Steel (ECCS)/Tin-Free Steel (TFS)
HJ GROUP leads the industry with advanced electrolytic chromium coating technology, delivering high-performance TFS for demanding global markets:
Key Features
● Corrosion Resistance: Chromium oxide layer (0.2-0.5g/m²) provides superior protection against sulfide and chloride attack
● Surface Quality: Mirror-like finish (Ra ≤0.8μm) supports high-definition lithographic printing
● Formability: Yield strength 240-340MPa with excellent deep-drawing capability
● Sustainability: Tin-free composition reduces environmental impact while maintaining recyclability
Applications
Food & Beverage Packaging: Beverage cans, soup containers, and ready-meal packaging. HJ GROUP’s TFS provides FDA/EFSA-compliant corrosion protection for acidic foods while maintaining product integrity.
Electronics & Appliances: Back covers for smartphones, battery cases, and refrigerator components. Combines high formability (Elongation ≥25%) with smooth surface finish for precision stamping.
Automotive Components:
1. Fuel tank liners, exhaust parts, and underbody shields
2. Chromium oxide coating offers 1000+ hours of salt spray resistance in harsh environments
Construction Solutions:
1. Roofing panels, siding, and HVAC ducts
2. UV-resistant coatings ensure 20+ years of outdoor durability with minimal maintenance
General Industrial Packaging:
1. Chemical drums, lubricant containers, and medical device packaging
2. FDA-approved coatings prevent contamination in sensitive applications
