The difference between stainless steel 300 series and 400 series

The 400 series stainless steel is an alloy of iron and carbon. This type of stainless steel has a martensitic structure and contains iron, which gives it magnetic properties. The 400 series stainless steel has excellent resistance to high-temperature oxidation and, compared to carbon steel, it has improved physical and mechanical properties. Most 400 series stainless steels can undergo heat treatment.

The 300 series stainless steel, on the other hand, is an alloy material that contains iron, carbon, nickel, and chromium. It is a non-magnetic stainless steel material and has better forgeability compared to the 400 series. Due to its austenitic structure, the 300 series stainless steel exhibits strong corrosion resistance in many environments and has good resistance to fracture caused by metal-induced stress corrosion. Furthermore, its material properties are not affected by heat treatment.

SUS304: It has good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties. It can be easily processed through operations such as stamping and bending, without hardening phenomenon through heat treatment. It is non-magnetic. It is widely used in household items (category 1 and 2 utensils), cabinets, indoor piping, water heaters, boilers, bathtubs, automotive components, medical devices, construction materials, chemical and food industries, agriculture, and ship components.
