SUMMARY
Stainless steel exhibits varying magnetic properties depending on its composition and crystal structure. The 400 series stainless steels, such as 440C, are generally magnetic, while the 300 series, including 304 and 316, are predominantly non-magnetic due to their austenitic structure. The presence of nickel reduces magnetism, while ferritic structures are magnetic. Additionally, temperature changes can induce phase transitions in austenitic stainless steels, potentially altering their magnetic properties.
PREREQUISITES
