ASTM A599 Tin Coated Steel Product Information -:- For detailed product information, please contact sales. -: ### **ASTM A599 Tin Coated Steel: Cold-Rolled Tin Mill Products** #### **1. Overview** ASTM A599 is a standard specification for **cold-rolled tin mill products** with **electrolytic tin coating**, commonly known as **tinplate**. This specification covers steel products that are electrolytically coated with tin on both sides, primarily used in packaging applications where corrosion resistance, formability, and food safety are critical. Tinplate combines the strength of steel with the protective and aesthetic qualities of tin, making it ideal for food and beverage containers. #### **2. Chemical Composition** The base steel composition varies by quality grade: | Element | Composition (%) | |---------|-----------------| | Carbon (C) | 0.03 - 0.13 | | Manganese (Mn) | 0.20 - 0.60 | | Phosphorus (P) | 0.02 max | | Sulfur (S) | 0.05 max | | Copper (Cu) | 0.06 - 0.20 | | Silicon (Si) | 0.02 max | **Coating Characteristics:** - **Coating Type**: Electrolytic tin deposition - **Coating Weight**: 0.25 to 1.50 lb/base box (typical) - **Coating Structure**: Pure tin layer with FeSn₂ intermetallic layer - **Surface Finish**: Bright, reflowed, or differential coatings available #### **3. Physical & Mechanical Properties** **Mechanical Properties (by Quality Grade):** | Property | MR Quality | L Quality | MC Quality | |----------|------------|-----------|------------| | **Tensile Strength** | 45-60 ksi | 50-65 ksi | 55-75 ksi | | **Yield Strength** | 35 ksi min | 40 ksi min | 45 ksi min | | **Elongation** | 20% min | 18% min | 15% min | | **Hardness (HR30T)** | 50-62 | 52-64 | 54-68 | **Coating Properties:** - **Corrosion Resistance**: Excellent for food and chemical products - **Solderability**: Superior soldering characteristics - **Lacquer Adhesion**: Excellent base for organic coatings - **Appearance**: Bright, attractive surface finish **Physical Properties (Typical):** - **Density**: 7.85 g/cm³ - **Electrical Conductivity**: Good for welding applications - **Magnetic Properties**: Ferromagnetic - **Thermal Conductivity**: 50-60 W/m·K #### **4. Product Applications** Tinplate is extensively used in packaging and other industries: **Food and Beverage Packaging:** - Food cans (vegetables, fruits, meats, fish) - Beverage cans (soft drinks, beer, juices) - Aerosol containers - Pet food containers **General Packaging:** - Paint and chemical containers - Oil and lubricant cans - Powder and cream containers - Decorative tins and boxes **Industrial Applications:** - Electrical component housings - Battery cases - Small machinery parts - Electronic enclosures **Consumer Products:** - Cookie tins and gift packages - Tobacco tins - Cosmetic containers - Musical instrument reeds #### **5. International Standards & Equivalents** | Region/Country | Standard | Equivalent Grade | Notes | |----------------|----------|------------------|-------| | **International** | **ISO 11949** | Tinplate | Cold-reduced electrolytic tinplate | | **Europe** | **EN 10202** | Tinplate | Cold reduced electrolytic tinplate | | **Japan** | **JIS G3303** | Tinplate | Electrolytic tinplate | | **China** | **GB/T 2520** | Tinplate | Cold-rolled electrolytic tinplate | **Coating Weight Designations:** | Coating Class | Tin Coating (lb/base box) | Equivalent (g/m²) | |---------------|--------------------------|-------------------| | **25** | 0.25/0.25 | 2.8/2.8 | | **50** | 0.50/0.50 | 5.6/5.6 | | **75** | 0.75/0.75 | 8.4/8.4 | | **100** | 1.00/1.00 | 11.2/11.2 | #### **6. Fabrication & Quality Assurance** **Forming and Fabrication:** - **Deep Drawing**: Excellent for can making processes - **Wall Ironing**: Suitable for DWI (Draw and Wall Ironed) processes - **Beading and Flanging**: Good for container reinforcement - **Seaming**: Ideal for double seaming operations **Welding and Joining:** - **Soldering**: Excellent solderability with traditional methods - **Welding**: Suitable for resistance welding - **Adhesive Bonding**: Compatible with food-grade adhesives - **Mechanical Joining**: Good for seaming and crimping **Surface Treatment and Printing:** - **Chemical Passivation**: Chromate treatment for enhanced corrosion resistance - **Lacquering**: Various lacquer systems for internal protection - **Printing**: Excellent for offset and lithographic printing - **Varnishing**: Protective varnish coatings available **Quality Control Requirements:** - **Coating Weight Tests**: Coulometric or X-ray methods - **Adhesion Tests**: Bend tests and impact tests - **Surface Analysis**: Microscopic examination for coating quality - **Corrosion Testing**: Salt spray and specialized food tests --- **Technical Advantages:** - **Superior Corrosion Protection**: Tin provides excellent barrier properties - **Excellent Formability**: Suitable for high-speed can making - **Food Safety**: Approved for direct food contact - **Recyclability**: 100% recyclable material - **Printability**: Excellent surface for high-quality printing **Design Considerations:** - **Coating Selection**: Choose appropriate tin coating weight for application - **Corrosion Requirements**: Consider product aggressiveness - **Forming Severity**: Match steel grade to forming requirements - **Decoration Requirements**: Plan for printing and coating processes **Service Limitations:** - **Temperature Limit**: Avoid temperatures above 232°C (tin melting point) - **Chemical Exposure**: Not suitable for strong alkaline solutions - **Mechanical Abuse**: Surface may scratch in rough handling - **Cost Considerations**: Higher cost compared to some alternatives **Disclaimer:** This technical information is for reference purposes only. For food packaging applications, consult the latest ASTM A599 specification and relevant food contact regulations. Material selection should consider specific product characteristics, and manufacturing processes must comply with food safety requirements and industry standards for container manufacturing. -:- For detailed product information, please contact sales. -: ASTM A599 Tin Coated Steel Specification Dimensions Size： Diameter 20-1000 mm Length <4482 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: ASTM A599 Tin Coated Steel Properties -:- For detailed product information, please contact sales. -:
