🎓 Why don't 304, 316 austenitic stainless steels stick to magnets?! 📌 Principle of non-magnetism

📌 The truth about 304, 316 stainless steel! Complete summary of the principle of non-magnetism, and the difference between ferrite and martensite! #stainless #magnet #austenite #non-magnetic metal 🧲 "Stainless steel doesn't stick to a magnet?" Is that true? Do you think stainless steel will stick to a magnet because it contains iron? But! It's completely different depending on the type. ✔️ Austenitic stainless steels such as 304 and 316 hardly stick to a magnet! ✔️ On the other hand, ferrite and martensitic stainless steels such as 430 and 410 stick to a magnet well. 🔬 Why are there stainless steels that stick to magnets and stainless steels that don't? The key is in the 'crystal structure'! Whether stainless steel is magnetic or not depends on how the iron is arranged in the crystal structure rather than 'whether it contains iron.' ✔️ Austenitic stainless steel (304, 316, etc.) : It contains iron, but it has an FCC (face-centered cubic) structure, so it is non-magnetic. It does not stick well to regular magnets. ✔️ Ferritic stainless steel (430, etc.) : It has a BCC (body-centered cubic) structure, and the ferromagnetic properties of iron are maintained, so it sticks well to magnets. ✔️ Martensitic stainless steel (410, 420, etc.) : It has strong magnetic properties thanks to the transformation structure created after heat treatment. It is often used for tools and blades. ✔️ Duplex stainless steel (2205, etc.) : It has a mixed structure of austenite and ferrite, so it is partially magnetic. 💡 The key is not 'whether there is iron', but what crystal structure it exists in! If the structure is FCC, it is non-magnetic, and if it is BCC, it is magnetic. 🏗️ Why is this important? – Essential knowledge for construction sites, pipe construction, precision equipment manufacturing, etc.! Distinguishing between magnetic and non-magnetic materials is very important in non-destructive testing (RT, MT, etc.), electromagnetic field generating equipment, induction heaters, medical devices, etc. Avoid mistakes when selecting stainless steel containers, semiconductor equipment parts, and piping materials! 📢 This video is recommended for these people! ✅ Engineers/industrial engineers/technical engineer candidates who are learning metal materials for the first time ✅ Pipers and welders who frequently handle stainless steel materials in field work ✅ Workers in plants, semiconductors, chemical engineering, and power generation ✅ Construction site managers, trainers – Can also be used as safety education materials for workers! 💡 Summary of key points learned in one video! ✔️ What is magnetism? Ferromagnetism/non-magnetism/paramagnetism concepts ✔️ The relationship between the structure of stainless steel and magnetism ✔️ 304 vs. 430, which one sticks to a magnet? ✔️ Why do we need non-magnetic metals? ✔️ Metal magnetism test method and application examples 📚 Practical explanations used in actual industrial sites! This video is not a simple theory lecture. It is a practical capacity-building lecture that starts from a small curiosity of "Why doesn't it stick to a magnet?" It is connected to material selection, inspection, and safety. 👍 Like & 🔔 Subscription is a great help in producing more practical education on metal materials! 📌 Please leave a comment on the metal material topic you are curious about~! 📌 #PlantEducation #AusteniticStainlessSteel #Non-MagneticMetal #304StainlessSteel #316StainlessSteel #MagneticTest #Ferromagnetism #Non-Magnetic #Martensite #Ferrite #DuplexStainlessSteel #StainlessSteelMagnet #ConstructionSiteEducation #MetalMaterialLecture #PlantPipe #SemiconductorPipe #MagneticTesting #Non-DestructiveTesting #PipeConstruction #WeldingMaterial #IndustrialEngineer #Technician #TechnicalEngineer #ComparisonofMagnetic #ReasonItDoesntStickToMagnet #MagneticField #ConstructionSafetyEducation #GovernmentSupportedEducation #MeisterHighSchool #Polytechnic #DepartmentofMechanicalEngineering #DepartmentofMaterialEngineering #DepartmentofChemicalEngineering #HundredMillionSalaryOccupation #PlantEmployment #On-SiteTechnicalEducation #SteelMaterials #BasicMetalKnowledge
