SUS304 Stainless Steel Clad Sheet

1. Corrosion resistance and cost

The surface SUS304 is equivalent to pure 304 in corrosion resistance, meeting the requirements of chemical lining; the salt spray test is over 1000 hours without red rust, the base layer has no penetration, the service life is 5 times longer than pure carbon steel, and the cost is 40%-60% lower than that of pure stainless steel plate.

2. Mechanical properties are suitable for complex working conditions

The tensile strength of the carbon steel base composite plate is ≥450MPa, meeting the strength requirements of GB150 medium and low pressure vessels; the -20℃ low temperature impact absorption energy is ≥27J (Q235B base), and the resistance to low temperature embrittlement is better than pure stainless steel, suitable for severe cold projects in the north.

SUS304 Clad Sheet Application

Petrochemical	Inner lining of crude oil storage tanks – replaces solid 304 with 50% cost savings
Architectural	Commercial curtain walls – 40% lighter than solid stainless steel, reducing transport and installation costs
Marine & Offshore	Yacht decks, port equipment – 304 surface resists chloride corrosion (rate: 0.03 mm/year); aluminum base reduces weight, improving fuel efficiency
Food & Pharmaceutical	Equipment housings – replaces solid 304 with 30% cost reduction, meets hygiene standards
Energy & Environmental	Solar collector plates (copper alloy base improves thermal conductivity by 2–3×); flue gas duct linings resist dew point corrosion while ensuring heat efficiency

Q: Is SUS304 stainless steel magnetic?
A: SUS304 is generally non-magnetic in the annealed state, but light magnetism may appear after cold working.

Q: How thick is the stainless steel layer?
A: Typically ranges from 0.1 mm to 2.0 mm depending on application and specification.

Q: Is it food-safe?
A: Yes, SUS304 is widely approved for food contact surfaces due to its hygienic properties.

Q: How do I maintain or clean the surface?
A: Regular cleaning with mild detergents and non-abrasive tools preserves its appearance and prevents corrosion.
