NITRONIC® 60 (UNS S21800)

NITRONIC® 60 stainless steel forgings are a premium choice for applications demanding wear resistance, high strength, and corrosion resistance. Their unique nitrogen-strengthened composition and compliance with ASTM, AMS, and NACE standards ensure reliability in aerospace, marine, and energy industries. These forgings are particularly suited for components exposed to friction, abrasion, and harsh chemical environments.

Descriptions

1. Chemical Composition

NITRONIC® 60’s unique composition combines nitrogen for strength and reduced nickel for cost efficiency:

2. Mechanical Properties

NITRONIC® 60 forgings exhibit outstanding mechanical properties in both ambient and elevated temperature conditions. Typical values in the solution-annealed condition are:

Room Temperature Properties

Elevated Temperature Performance

3. Common Forging Product

Forged Valve Stems

Forged Bushings

Forged Fasteners

Forged Pump Shafts

Forged Actuator Components

4. Key Advantages

Unmatched Galling Resistance: Ideal for threaded and sliding components.

High Strength: Superior to 300-series stainless steels (e.g., 2x yield strength of 304).

Corrosion Resistance: Resists pitting, crevice corrosion, and chloride stress corrosion cracking (SCC).

Cost-Effective: Reduced nickel content lowers material costs compared to high-nickel alloys.
