Five Types of Stainless Steel
Austenitic Stainless Steel (200 & 300 Series)
The most common type, known for excellent corrosion resistance, weldability, and formability.
304 (A2 Stainless Metal)
- Composition: 18% Cr, 8% Ni
- Properties: High corrosion resistance, non-magnetic, excellent formability
- Uses: Kitchen equipment, food processing, chemical tanks
316 (Marine Grade Stainless Metal)
- Composition: 16-18% Cr, 10-14% Ni, 2-3% Mo
- Properties: Superior corrosion resistance (especially against chlorides), stronger than 304
- Uses: Marine environments, medical devices, pharmaceutical equipment
321
- Composition: Similar to 304 but with titanium (Ti) for stabilization
- Properties: Resistant to high temperatures, prevents carbide precipitation
- Uses: Aircraft exhaust systems, heat exchangers
Ferritic Stainless Steel (400 Series)
Martensitic Stainless Steel (400 & 500 Series)
Magnetic, with good corrosion resistance but lower nickel content.
430
- Composition: 16-18% Cr, <0.12% C
- Properties: Moderate corrosion resistance, magnetic, cost-effective
- Uses: Automotive trim, appliances, decorative applications
446
- Composition: Higher Cr (23-30%) with added Mo
- Properties: Excellent heat and oxidation resistance
- Uses: High-temperature applications like furnace parts

Duplex Stainless Steel (Combination of Austenitic & Ferritic)
Higher strength and better chloride resistance than standard austenitic grades.
- 2205 (UNS S31803/S32205)
- Composition: 22% Cr, 5% Ni, 3% Mo, 0.15% N
- Properties: High strength, excellent stress corrosion cracking resistance
- Uses: Oil & gas pipelines, chemical processing, desalination plants
Precipitation-Hardening Stainless Steel
Can be heat-treated for extreme strength.
- 17-4 PH (AISI 630)
- Composition: 15-17.5% Cr, 3-5% Ni, 3-5% Cu
- Properties: High strength, good corrosion resistance
- Uses: Aerospace components, nuclear reactors, high-stress applications
How to Choose the Right Stainless Steel Grade?
- Corrosion resistance needed? (316 for marine, 304 for general use)
- Strength requirements? (Duplex or martensitic for high strength)
- Temperature exposure? (321 or 446 for high heat)
- Budget constraints? (430 is more affordable than 316)
