Hard Temper Tinplate Coil - High-Strength Electrolytic Tin Coated Steel Coil

Hard temper tinplate coil represents a premium-grade electrolytic tin-coated steel product engineered for applications demanding exceptional rigidity and structural integrity. This specialized cold-rolled steel substrate receives a precisely controlled tin coating through electroplating, delivering superior formability resistance and mechanical strength compared to standard temper grades. Manufactured to meet stringent international standards including JIS G3303, ASTM A623, and EN 10202, hard temper tinplate coil serves critical roles in rigid container manufacturing, industrial packaging, and structural components where dimensional stability under stress is paramount.

What is Hard Temper Tinplate Coil?

Hard temper tinplate coil is cold-rolled low-carbon steel sheet with electrolytic tin coating on both surfaces, processed to achieve Rockwell hardness values exceeding HR 30T 60, corresponding to T-5 or T-6 temper designations per international standards. The material exhibits tensile strength ranging from 550-680 MPa with minimal elongation properties (2-6%), making it the preferred choice for applications requiring maximum stiffness and resistance to deformation during high-speed forming operations.

Hard Temper Tinplate Coil Technical Specifications

Base metal thickness ranges from 0.15mm to 0.49mm with tin coating weight options of 2.8g/m² to 11.2g/m² per surface (E2.8/2.8 through E11.2/11.2 designations). The substrate steel grade typically conforms to MR-type (low-carbon aluminum-killed steel) with carbon content limited to 0.13% maximum and manganese content between 0.30-0.60% per ASTM A623 Section 6.1. Standard coil dimensions include widths from 600mm to 1050mm and coil weights up to 12 metric tons, with inner diameter of 508mm (20 inches) conforming to ISO 11949 specifications.

Our hard temper tinplate coil delivers mill-direct competitive pricing combined with guaranteed compliance to JIS G3303:2012 and EN 10202:2001 chemical composition requirements. Each production lot undergoes rigorous testing including Rockwell hardness verification, tin coating weight measurement via coulometric stripping per ASTM A624, and surface quality inspection under ISO 11949 Class A standards. We maintain extensive inventory across temper grades T-5 (HR 30T 60-64) and T-6 (HR 30T 64+) with same-day quotation response and technical consultation from our metallurgical engineering team.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard MOQ for hard temper tinplate coil is 25 metric tons per specification (thickness/coating/temper combination), with flexibility for consolidated orders combining multiple grades. Trial orders of 10 tons minimum are available for first-time customers requiring material qualification testing, subject to mill scheduling availability and applicable surcharges for non-standard production runs.

Hard temper tinplate coil supplier

Do you provide material test certificates?

Yes, every shipment includes EN 10204 Type 3.1 mill test certificates documenting chemical composition analysis per ASTM E1019, mechanical properties testing per ASTM A370, tin coating weight verification, and temper grade confirmation. Additional certifications available upon request include RoHS compliance declarations, REACH SVHC statements, and FDA food contact compliance documentation per 21 CFR 175.300 for applicable coating systems.

What is the typical delivery time?

Lead time for in-stock standard specifications averages 15-20 working days from purchase order confirmation to port of loading, including mill production scheduling, quality inspection, and export documentation processing. Custom specifications requiring special rolling programs or non-standard coating weights may extend to 35-45 days depending on mill capacity and raw material procurement cycles for specific steel grade requirements.

Can you cut to custom sizes?

We offer precision slitting services to customer-specified widths with tolerance of ±0.5mm, minimum slit width of 100mm, and maximum of 1050mm based on master coil dimensions. Sheet cutting to length is available through our processing partners with tolerances per ASTM A623 Table 4 requirements, minimum sheet length 500mm, and burr-free edge quality suitable for direct stamping operations without secondary deburring.

Acceptable Quality with Initial Communication Issues
Ordered 12-ton trial quantity of 0.24mm hard temper tinplate for evaluation across T-5 and T-6 grades. Material quality met specifications with proper EN 10204 Type 3.1 certificates. Initial quotation response took 3 days rather than advertised same-day service, and there was confusion regarding MOQ requirements for mixed-grade orders. However, supplier resolved concerns professionally and applied reasonable surcharge for non-standard production run. Final delivered material performed adequately in our stamping trials. Would consider for future orders now that account relationship is established.

Perfect Solution for Food Can Manufacturing
Sourced 42 tons of MR-grade hard temper tinplate (0.21mm, T-5 temper, E5.6/5.6) for vegetable can production line. Chemical composition analysis showed aluminum-killed steel with 0.11% carbon and 0.48% manganese, ideal for welding operations. Material certificates documented compliance with both ASTM A623 Section 6.1 and our internal food safety standards. Elongation properties at 4.2% provided sufficient formability for three-piece can body formation while maintaining required stiffness. Delivered to Santos port in 16 days with complete REACH SVHC statements for European export compliance.

Solid Material for Structural Component Manufacturing
Purchased 30 tons of 0.35mm T-6 hard temper tinplate for electrical enclosure fabrication in harsh desert environment. Material demonstrated excellent corrosion resistance with E11.2/11.2 heavy coating specification. Mechanical properties exceeded our requirements with measured tensile strength 638 MPa. Pricing competitive when compared quotes from 4 suppliers. Sheet cutting service to 1200x2400mm dimensions had acceptable edge quality though required minor deburring for some pieces. Lead time was 22 days to Jebel Ali port, slightly longer than quoted 18 days.
