400 Series Stainless Steel Plate/Sheet

Key Features

• Good Corrosion Resistance
  Moderate resistance to oxidation, acids, and moisture, making it ideal for applications exposed to moderate environments.
• High Strength & Hardness
  Offers superior mechanical properties compared to austenitic grades, particularly in martensitic variants like 410 and 420.
• Magnetic Properties
  Unlike the 300 series, 400 series stainless steel is magnetic, making it suitable for applications requiring magnetic response.
• Heat & Wear Resistance
  Some grades, such as 410 and 446, offer excellent resistance to high temperatures and wear, making them suitable for industrial and thermal applications.
• Cost-Effective Alternative
  Generally more affordable than 300 series stainless steel while still offering excellent performance.

Grade	Key Properties	Typical Applications
409	Heat-resistant, corrosion-resistant	Automotive exhaust systems, catalytic converters
410	High strength, good corrosion resistance	Cutlery, valves, turbine blades, fasteners
