The 400 series stainless steel is primarily composed of iron, chromium, and carbon, with some grades containing small amounts of nickel and manganese. This composition gives it high hardness and excellent wear resistance, making it ideal for applications like cutlery, valves, pumps, and automotive parts.
Unlike the 300 series, the SS 400 series is magnetic. This is because it falls under the ferritic and martensitic categories of stainless steel, which have a different internal structure that allows for magnetism. This magnetic property can be particularly advantageous in applications where magnetic attraction is required.
Actually there are two simple core rules to tell if stainless steel is magnetic.
First off, the material has to contain iron, and all stainless steel definitely has iron inside.
Second, its internal crystal structure has to be ferritic or martensitic. Only when both conditions are satisfied will the steel show magnetism.
Most common 400 series stainless steel belongs to ferritic type.
With stable ferritic structure plus enough iron content inside, it is naturally magnetic. Popular grades like 430, 410 all can be attracted by magnets easily. A few individual specifications have weaker magnetism, which is just normal material feature, won’t affect later stamping, processing or daily use at all.
At Normandy Metal, we pride ourselves on offering top-notch 400 series stainless steel products. Our materials undergo rigorous quality control to ensure that every batch meets international standards. Whether you’re looking to manufacture cutlery or industrial equipment, our 400 series stainless steel will meet your needs.

No need for professional testing tools at all.
Just take an ordinary magnet and stick it on the steel surface. If it sticks firmly, this steel has obvious magnetism; if there is almost no attraction, it is non-magnetic type. This easy trick helps you quickly distinguish material types when receiving goods or placing orders.
