One of the most frequently asked questions when purchasing duplex stainless steel bars is: Is 1.4462 stainless steel magnetic? The magnetic properties of 1.4462 (also known as Duplex 2205 stainless steel) are crucial for engineers, purchasing managers, and end-users, especially in industries such as chemical, marine, shipbuilding, and oil and gas.
This article will explain why 1.4462 stainless steel is magnetic, how strong its magnetism is, and whether its magnetism affects its performance or quality.
what Is 1.4462 Stainless Steel bar?
1.4462 stainless steel bar is a high-strength, corrosion-resistant duplex stainless steel (also known as UNS S31803 or 2205) that blends properties of both austenitic and ferritic steels, offering excellent resistance to pitting and stress corrosion cracking, making it ideal for demanding environments in chemical processing, oil & gas, and marine applications. Its unique structure provides about double the yield strength of standard austenitic steels, combined with good weldability and wear resistance.
Is 1.4462 Stainless Steel Bar Magnetic?
1.4462 stainless steel rods have moderate magnetic properties. They are more magnetic than austenitic stainless steels (304, 316), but less magnetic than fully ferritic or martensitic stainless steels.
In practical applications: magnets can be attracted to 1.4462 stainless steel rods. The magnetic response may vary slightly depending on the heat treatment and processing methods.
Does Magnetism Affect the Performance of 1.4462?
No. Magnetism does NOT reduce performance or quality.
The magnetic property:
❌ Does not mean poor corrosion resistance
❌ Does not indicate wrong material
❌ Does not affect mechanical strength
In fact, the ferritic phase that causes magnetism also contributes to:
Higher yield strength
Better resistance to stress corrosion cracking
What is the chemical composition of 1.4462 stainless steel?
1.4462 (Duplex 2205) stainless steel typically contains 21–23% Cr, 4.5–6.5% Ni, 2.5–3.5% Mo, and ~0.15% N, providing a balanced austenitic–ferritic microstructure with high corrosion resistance.
What is the hardness of 1.4462 stainless steel?
The typical hardness of solution-annealed 1.4462 stainless steel is ≤290 HB (approximately 30 HRC), offering a strong combination of strength and toughness.
What is the density of 1.4462 stainless steel?
1.4462 stainless steel has a density of approximately 7.8 g/cm³, slightly lower than austenitic grades such as 304 and 316.
What is the yield strength of 1.4462 stainless steel?
The minimum 0.2% proof (yield) strength of 1.4462 stainless steel is ≥450 MPa, nearly twice that of 304/316 stainless steel.
What is the maximum service temperature of 1.4462 stainless steel?
1.4462 stainless steel is generally recommended for continuous service up to about 280–300°C, above which phase embrittlement may occur.
What is the difference between 1.4462 and 1.4410 stainless steel?
Compared with 1.4462, 1.4410 (Super Duplex 2507) contains higher Cr, Mo, and N levels, delivering ~25–40% higher pitting resistance (PREN ≥40 vs ~35) and greater strength, but at a higher material cost.
