‌Property‌

‌304 Stainless Steel‌ Plate

‌316 Stainless Steel‌ Plate

‌Composition‌

~18% Cr, 8-11% Ni, no Mo

~16-18% Cr, 10-14% Ni, ‌2-3% Mo‌

‌Corrosion Resistance‌

Good for general environments; ‌susceptible to pitting in saltwater or coastal areas‌

‌Excellent resistance to chlorides, acids, and industrial chemicals‌

‌High-Temperature Use‌

Up to 870°C (short-term)

Up to ‌925°C (long-term)‌, more stable under heat

‌Tensile Strength‌

≥520 MPa

≥620 MPa - ‌higher strength and durability‌

‌Cost‌

Lower - widely used in everyday applications

‌30-50% more expensive‌ due to Mo and higher Ni

‌Typical Applications‌

Kitchenware, food processing, architectural trim

Medical devices, marine hardware, chemical tanks, offshore structures

‌Application Area‌

‌304 Stainless Steel‌ Plate

‌316 Stainless Steel‌ Plate

‌Food & Kitchen Equipment‌

Widely used for sinks, countertops, cookware, and storage due to good formability and hygiene

Less common; used only when higher durability is needed

‌Architectural & Decorative Use‌

Common in indoor railings, facades, signage, and elevator panels (urban/non-coastal)

Preferred for coastal buildings, high-rise exteriors, and humid environments

‌Chemical Exposure‌

Resists mild acids and organic compounds

‌Superior resistance to strong acids, alkalis, and industrial chemicals‌

‌Marine & Coastal Environments‌

Not recommended - prone to pitting in saltwater

‌Ideal for boat fittings, piers, offshore platforms, and coastal structures‌

‌Medical Devices‌

Used in non-implant tools and equipment housings

Preferred for surgical instruments and implants due to biocompatibility

‌Pharmaceutical Industry‌

Acceptable for general processing equipment

‌Standard choice for reactors and piping due to higher purity and cleanability‌

‌High-Temperature Service‌

Good oxidation resistance up to ~870°C

Slightly better performance under prolonged heat stress

‌Welded Structures‌

Suitable for general welding

‌316L (low carbon) version prevents weld decay, ideal for critical joints‌

‌Cost-Sensitive Projects‌

‌Preferred for budget-conscious applications with low corrosion risk‌

Used only when performance justifies the 20-30% higher cost
