T3 Temper MR Grade Electrolytic Tin Plate Coils with Continuous Annealing for Food Cans

T3 Temper MR Grade Electrolytic Tin Plate Coils with Continuous Annealing for Food Cans

Product Description

This product is a specialized Electrolytic Tin Plate (ETP) coil, manufactured from prime MR-grade steel and processed through a Continuous Annealing (CA) line. Characterized by its T3 temper designation, this tinplate offers an optimal balance of good ductility and moderate strength, making it exceptionally suitable for a wide range of general-line food packaging applications. The continuous annealing process ensures superior uniformity in mechanical properties and microstructure across the entire coil length compared to batch annealing, leading to more consistent performance during high-speed fabrication. The electrolytic tin coating provides reliable, sacrificial corrosion resistance, protecting both the integrity of the metal and the quality of packaged contents such as sardines, tuna, vegetables, and fruits. Supplied in coil form, it is engineered for efficiency in automated can-making lines that require reliable formability for drawing and stamping operations.

Features & Characteristics

• Optimized T3 Temper: Provides an excellent balance between formability and strength, ideal for manufacturing can bodies and components that require moderate drawing without excessive hardening.

• Prime MR Steel Base: Utilizes MR-grade steel, known for its excellent drawing quality, consistent weldability, and suitability for food contact applications.

• Continuous Annealing (CA) Consistency: The CA process delivers uniform hardness and excellent shape, minimizing yield loss and ensuring predictable behavior in high-volume stamping and forming.

• Reliable Corrosion Barrier: The electrolytically applied tin coating acts as a protective layer against oxidation and internal chemical attack from food products.

• Versatile Processing Compatibility: Suitable for various secondary processing services including decoiling, cutting, welding, bending, and punching, offering flexibility to manufacturers.

Key Advantages

Choosing these T3 CA tinplate coils translates to enhanced production stability and material efficiency. The consistent quality reduces tool wear and minimizes breakage or wrinkling during forming, directly improving production yields. The coil format facilitates continuous, high-speed feeding into blanking or stamping presses, optimizing line throughput. Furthermore, the material's proven performance in food packaging ensures compliance with industry standards for safety and durability, while its recyclability supports sustainable manufacturing initiatives.

Frequently Asked Questions (FAQ)

Q1: What are the typical applications for T3 temper tinplate?

A1: T3 temper is a versatile, general-purpose grade commonly used for the bodies and ends of food cans containing fish, meat, vegetables, and fruits. It is well-suited for applications requiring a good level of formability combined with adequate strength for filling, seaming, and handling.

Q2: Why is Continuous Annealing (CA) preferred for coil products?

A2: Continuous Annealing provides more homogeneous mechanical properties along the entire strip length and across its width. This consistency is crucial for coil processing, as it ensures stable forming behavior and reduces the risk of shape defects, leading to higher productivity and less scrap.

Q3: How does MR grade steel benefit food can manufacturing?

A3: MR (Miller Rated) steel has controlled chemical composition, particularly low levels of residual elements like copper, nickel, and chromium. This results in superior corrosion resistance after drawing and excellent weldability, making it the standard and most cost-effective choice for most food can applications.

Q4: Can you supply custom slit widths or inner diameters for the coils?

A4: Yes. We can customize the slit width within the 600-1050mm range and provide coils on standard inner diameters (typically 508mm or 610mm) to fit your specific decoiling equipment.

Q5: What quality documentation accompanies shipment?

A5: Each shipment is supported by a detailed Mill Test Certificate, which provides traceability and confirms compliance with specifications for chemical composition, mechanical properties (temper, hardness), coating weight, and surface quality. Additional third-party inspection reports (e.g., SGS) can be arranged.
