Greek Ascoloy 418

Key Characteristics and Composition
Type: Hardenable Martensitic Stainless Steel.
Key Elements: Chromium (12-14%), Nickel (1.8-2.2%), and Tungsten (2.5-3.5%) are crucial for its high-temperature strength and resistance.
Hardening:It is an extremely deep-hardening grade, meaning a wide range of mechanical properties can be achieved through heat treatment and tempering. Properties
High-Temperature Strength: Designed for service temperatures up to 1200°F (649°C).
Creep Resistance: Offers superior resistance to creep, or slow deformation under high stress and temperature.
Corrosion Resistance: Good resistance to oxidation, scaling, atmospheric corrosion, and weak acids.
Resistance to Cracking: Exhibits higher resistance to tempering and stress-corrosion cracking than standard 12% chromium stainless steels.
Applications
Aerospace: Used in jet engines and gas turbines for compressor blades, vanes, and other high-stress parts.
Turbines: Employed in steam turbine buckets and blades.
Other High-Temperature Parts: Suitable for high-temperature bolts and high-stress components.
