1. Key Properties
SAE 3415 (also known as 14NiCr18) is a high-quality, nickel-chromium alloy steel that combines excellent toughness, hardenability, and good wear resistance. The addition of nickel enhances its strength and resistance to corrosion, while chromium provides superior hardenability, ensuring the material retains its strength under high-stress conditions. This alloy is designed for use in high-load and demanding applications where strength, impact resistance, and fatigue resistance are crucial. The round bar form ensures that it can be easily machined into precise components with high dimensional accuracy.
