Stainless steel AISI 430 / EN 1.4016

Stainless Steel AISI 430 / EN 1.4016: Properties, Applications, and Features

✅ General Technical Characteristics

Stainless steel AISI 430 (EN 1.4016) is a ferritic stainless steel with a high chromium content, known for its good corrosion resistance, moderate mechanical strength, and excellent machinability. Due to its low nickel content, this alloy is a cost-effective alternative to austenitic grades such as AISI 304.

Main Characteristics:

• High corrosion resistance in moderately aggressive environments.
• Good wear resistance and mechanical strength.
• Excellent polishing and machining capabilities.
• High oxidation resistance at temperatures up to 800°C.
• Magnetic properties, distinguishing it from austenitic stainless steels.

🔬 Chemical Composition AISI 430 / EN 1.4016 (%):

• Carbon (C): ≤ 0.08
• Silicon (Si): ≤ 1.0
• Manganese (Mn): ≤ 1.0
• Phosphorus (P): ≤ 0.040
• Sulfur (S): ≤ 0.030
• Chromium (Cr): 16.0 – 18.0
• Nickel (Ni): ≤ 0.5

💡 The high chromium content provides good corrosion resistance, while the low nickel content makes this alloy economically advantageous.

🏭 Applications

Steel AISI 430 (EN 1.4016) is widely used in household appliances, decorative elements, and industrial structures.

Main Application Areas:

• Household appliances (ovens, refrigerators, dishwashers).
• Food industry (kitchen equipment, range hoods, food processing surfaces).
• Automotive industry (decorative parts, exhaust systems, cladding).
• Construction and architectural elements (railings, cladding panels, door structures).
• Manufacturing of tanks, containers, and reservoirs for liquid storage.

📊 Mechanical Properties

• Tensile Strength (Rm): 450 – 650 MPa
• Yield Strength (Rp0.2): ≥ 280 MPa
• Hardness (HB): ≤ 200 HB
• Elongation (A5): ≥ 22 %

⭐ Features

• Good corrosion resistance – suitable for use in humid and mildly aggressive environments.
• High mechanical strength – withstands mechanical loads well.
• Magnetic properties – distinguishes it from austenitic stainless steels.
• Cost-effectiveness – an affordable alternative to AISI 304 due to reduced nickel content.
