Three-Layer Metal Clad Plates

Structural Features

Symmetrical high-corrosion-resistance structure: both outer layers are 316L, core layer is 304.

Symmetrical economical structure: both outer layers are 304, core layer is 201.

Corrosion Resistance

Extremely strong: 316L contains molybdenum (Mo), offering excellent resistance to chloride ions (e.g., seawater, salt spray) and acidic environments.

Good: The 304 surface layer can withstand normal atmospheres,moisture, and mildly corrosive media, but is unsuitable for high-salinity or strong acid/alkali conditions.

Mechanical & Processing Properties

Excellent high-temperature/non-magnetic performance: 316L has slightly lower high-temperature strength than 304, but offers good plasticity and toughness, and remains non-magnetic after processing.

Prone to work hardening: 304 has good hot workability for stamping and bending, but cold working readily induces deformation martensite, leading to increased magnetism and hardening.

Cost

Cost-effective: Using lower-cost 304 stainless steel as the core layer significantly reduces overall material cost while maintaining high corrosion resistance.

Cost-effective: Using lower-cost 201 stainless steel as the core layer significantly reduces overall material cost while ensuring good surface quality.

Typical Applications

Coastal building facades, seawater desalination equipment, chemical plants, food processing equipment, medical devices, and other fields requiring extremely high corrosion resistance and cleanliness.

High-end decoration, elevators, cabinets, indoor piping, general chemical storage tanks, and structural components in dry environments.
