Real-world Performance Testing

1. 4-Month Industrial Scene Practical Test

• Test Duration: 4 consecutive months of continuous industrial commissioning
• Test Scenarios: Precision electronic component assembly, new energy battery connector processing, medical miniature accessory manufacturing, precision mechanical stamping
• Test Standard: Comply with GB/T 3280-2015 stainless steel strip precision manufacturing standard, test dimensional accuracy, surface finish, corrosion resistance and stamping toughness in full dimension
• Key Findings: For high-end industrial processing, dimensional precision and performance stability are far more important than basic hardness and thickness; this is the core design and production philosophy of qihong high precision stainless steel strip.

2. Ultra-high Dimensional Precision Performance

A one-month precision comparison test intuitively reflects the performance gap between qihong high precision stainless steel strip and ordinary stainless steel strips in industrial processing:

• Ordinary stainless steel strip: Thickness tolerance ±0.05mm~±0.2mm, prone to fitting deviation during precision stamping, with a product defective rate of 8%-12%.
• qihong high precision stainless steel strip: Thickness tolerance stably controlled within ±0.001mm, width tolerance ±0.002mm, flatness error less than 0.02mm/m, zero fitting deviation in precision assembly, and the product defective rate is reduced to less than 1.5%.
• The core precision guarantee technologies for the product include:
• Multi-pass precision rolling process: Adopt 12-pass progressive rolling to evenly distribute material stress and eliminate dimensional deviation.
• Constant temperature stress relief annealing: Intelligent constant temperature heat treatment to avoid material deformation and ensure long-term dimensional stability.
• Online laser precision detection: Real-time monitoring of strip thickness and flatness during production, automatic correction of process parameters.

3. Excellent Corrosion Resistance & Structural Stability

Aiming at the problems of easy rust and performance attenuation of ordinary stainless steel strips in humid, high-temperature and corrosive industrial environments, qihong high precision stainless steel strip has passed professional environmental simulation tests:

• Test conditions: 500-hour salt spray test, 80℃ high temperature and 90% high humidity continuous aging test
• Test results: The strip surface has no oxidation, rust or peeling, the tensile strength and hardness remain unchanged, and the corrosion resistance is 42% higher than that of ordinary 304 stainless steel strips, which can adapt to long-term harsh industrial environment operation.
• This stable corrosion resistance ensures that the product will not fail due to environmental factors after being made into precision parts, effectively reducing equipment maintenance and replacement costs for industrial enterprises.

4. Superior Processing & Matching Performance

Compared with ordinary stainless steel strips with poor toughness and difficult precise processing, qihong high precision stainless steel strip has optimized material ratio and processing technology, with more excellent stamping, bending and welding performance. The actual processing test verifies that the product's finished product matching accuracy is increased by 35%.
