do magnets stick to 430 stainless steel？

Yes — magnets stick strongly to 430 stainless steel.

430 stainless steel (AISI 430 / UNS S43000 / SUS430 / 1.4016 / X6Cr17) is a ferritic stainless steel, and ferritic stainless steels are magnetic in all conditions (annealed, cold-rolled, or lightly work-hardened).

Why Magnets Stick to 430 Stainless Steel

• Crystal structure: Ferritic stainless steels have a body-centered cubic (BCC) atomic arrangement, which is inherently magnetic (ferromagnetic).
• Chromium content(16–18%): Stabilizes the ferritic phase without forming non-magnetic austenite.
• No nickel(or very low ≤0.75%): Nickel is the element that makes austenitic grades (like 304 and 316) non-magnetic in the annealed state. 430 has almost none, so it stays strongly magnetic.

You can test this yourself: a standard fridge magnet, neodymium magnet, or even a weak refrigerator magnet will stick firmly to 430 stainless steel — whether it's a 2B, BA, NO.4, or HL finish, annealed or cold-worked.

Comparison with Other Common Grades

Practical Examples Where Magnetism Matters

• Refrigerator doors & panels— 430 is magnetic so magnetic clips, notes, and decorations stick perfectly (very common in home appliances).
• Kitchen knife holders— Magnetic 430 backs allow knives to stick securely.
• Automated production lines— Magnetic handling and separation systems work easily with 430 parts.
• Magnetic sensors & switches— 430's strong magnetic response is useful in electrical and appliance components.

Does Cold Rolling or Welding Affect Magnetism?

No — 430 remains strongly magnetic in all conditions:

• Annealed
• Cold rolled / work-hardened
• Lightly welded (HAZ stays ferritic)

Only extreme cold working in some ferritics can slightly reduce magnetism — not an issue with normal 430 processing.
