・ Certification: ISO 12944 indoor durability
・ Value: 35% cost reduction vs. 304 alternatives

Mingli Metal provides 304 stainless steel laser cutting, hydraulic forming, and electrolytic polishing for medical, food, and architectural applications. Compliant with GB 4806.9 food-grade metal fabrication standards. Suitable for hydraulic-formed 304 stainless steel medical instrument parts, electrolytic-polished 304 stainless steel food processing equipment, and laser-cut 304 stainless steel architectural cladding.

Key Attributes:
・ Composition: Cr 18-20% + Ni 8-10.5%
・ Corrosion Resistance: Weak acid/alkali (pH 2-9), salt spray >480hrs

Advantages:
✅ Rust-resistant metal processing: Near-zero corrosion in daily use
✅ Crack-free forming: >40% elongation, DR=2.0 deep drawing
✅ Welding efficiency: Low hardening allows no-anneal welds

Classic Case: Commercial Kitchen Sink Production
・ Process: Laser cutting → Hydraulic forming → Electro-polishing (Ra≤0.1μm)
・ Certification: NSF food contact
・ Durability: 15+ year lifespan
