AISI 410 / 1.4006 Stainless Steel

✅ General Technical Characteristics

Stainless steel AISI 410 (EN 1.4006) is a martensitic stainless steel known for its high mechanical strength, hardness, and moderate corrosion resistance. Due to its ability to undergo heat treatment, this steel gains increased wear resistance and hardness, making it suitable for use in high-load components.

Main Characteristics:

• High strength and hardness after heat treatment.
• Moderate corrosion resistance in mildly aggressive environments.
• Good machinability and polishability.
• Heat resistance up to 600°C.
• Suitable for mechanically stressed components.

🔬 Chemical Composition AISI 410 / EN 1.4006 (%):

• Carbon (C): 0.08 – 0.15
• Silicon (Si): ≤ 1.0
• Manganese (Mn): ≤ 1.5
• Phosphorus (P): ≤ 0.040
• Sulfur (S): ≤ 0.030
• Chromium (Cr): 11.5 – 13.5
• Nickel (Ni): ≤ 0.75

💡 The presence of chromium ensures corrosion resistance, while carbon allows for hardening and increased strength.

🏭 Applications

Steel AISI 410 (EN 1.4006) is widely used across various industries due to its combination of strength, wear resistance, and corrosion resistance.

Main Application Areas:

• Production of blades, knives, and cutting tools.
• Manufacturing of pump, valve, and turbine components.
• Automotive and mechanical engineering industries.
• Food industry (components for equipment in contact with food products).
• Petrochemical industry (pipeline and reservoir components).

📊 Mechanical Properties

• Tensile Strength (Rm): 500 – 750 MPa
• Yield Strength (Rp0.2): ≥ 250 MPa
• Hardness (HB): 180 – 250 HB (before heat treatment), 300 – 450 HB (after heat treatment)
• Elongation (A5): ≥ 20 %

⭐ Features

• High wear resistance – ideal for parts subjected to mechanical stress.
• Heat resistance – maintains mechanical properties at temperatures up to 600°C.
• Hardenability – gains additional hardness after heat treatment.
• Good machinability – easily processed and polished.
• Limited corrosion resistance – recommended for use in low-aggressiveness environments.
