409 Ni (Nickel-Modified) Stainless Steel

09 Ni Stainless Steel is a nickel-modified variation of standard Type 409, designed to enhance corrosion resistance, toughness, and weld-ability. With improved strength and durability, 409 Ni is an ideal choice for applications exposed to high temperatures and demanding environments.

Key Features & Benefits

• Enhanced Corrosion Resistance – The addition of nickel improves resistance to oxidation and harsh conditions.
• Superior Weld-ability & Form-ability – Easier to fabricate for complex shapes and high-performance applications.
• High-Temperature Performance – Performs well in extreme heat, making it ideal for exhaust and heat-exchange systems.
• Cost-Effective Alternative – Provides improved performance over standard 409 while remaining economical.

Common Applications

409 Ni Stainless Steel is widely used in:

• Automotive and non-automotive exhaust systems
• Power generation and heat exchangers
• Silencers and fuel filters
• Agricultural and industrial equipment
• Furnaces, woodstoves, and transformers
• Tubing and structural components

Specifications & Availability

Available in Hot Rolled Annealed and Pickled (HRAP) #1 in .187” to .490” thickness and Cold Rolled 2B or 2D finishes in .006” to .157” thickness. Both finishes meet industry standards, including ASTM and ASME specifications.
