We select top-grade stainless steel raw materials with stable chemical composition, matching different high-end industrial application scenarios:
303 Stainless Steel: Good machinability, suitable for precision stainless steel stamping parts with complex threads and slots;
304 Stainless Steel: Balanced corrosion resistance and cost, ideal for general high-end industrial equipment components;
316L Stainless Steel: Molybdenum-added for seawater/chemical corrosion resistance, for marine corrosion-resistant stainless steel stamping parts and aerospace components;
All materials are accompanied by official material certification to ensure product traceability.
Aiming at the high hardness and toughness of stainless steel, we adopt a specialized processing process: Product Design & Material Selection → High-Precision Laser Cutting → CNC Bending → Argon Arc Welding (stainless steel-specific) → Precision Machining → Stainless Steel Surface Treatment → Salt Spray Test → Quality Inspection → Anti-Oxidation Packaging → Shipping. Each process is optimized for stainless steel to avoid material deformation and oxidation.
