The chemical and Tensile test of 304 And 316 Stainless Steel Plate

‌Property‌	‌304 Stainless Steel‌ Plate	‌316 Stainless Steel‌ Plate
‌Chemical Composition‌
Chromium (Cr)	18–20%	16–18%
Nickel (Ni)	8–10.5%	10–14%
Molybdenum (Mo)	‌None‌	‌2–3%‌ - key for chloride resistance
Carbon (C)	≤ 0.08%	≤ 0.08% (≤ 0.03% in 316L)
Manganese (Mn)	≤ 2.0%	≤ 2.0%
Silicon (Si)	≤ 1.0%	≤ 0.75%
Phosphorus (P)	≤ 0.045%	≤ 0.045%
Sulfur (S)	≤ 0.03%	≤ 0.03%
‌Mechanical Properties‌ (Annealed)
Tensile Strength	≥ 520 MPa	≥ ‌620 MPa‌ - higher strength
Yield Strength (0.2% offset)	≥ 205 MPa	≥ ‌290 MPa‌
Elongation at Break	≥ 40%	≥ 40%
Hardness (Brinell)	≤ 201 HB	≤ 146–152 HB
Density	7.93 g/cm³	‌7.98 g/cm³‌ - slightly heavier
Magnetic Permeability	Generally non-magnetic (may become slightly magnetic after cold working)	Similar behavior - austenitic structure remains non-magnetic in annealed state

The difference between 304 And 316 Stainless Steel Plate

‌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

Different Applications

‌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
