Jakie Właściwości Ma Stal? I STALOWE FAKTY #7

🔍 What properties does steel have and how do we test them? In this episode, we take a look at what really determines steel's behavior in practice. I discuss mechanical, technological, and physical properties – and show how they are tested in engineering practice. In the video, you'll learn, among other things: ✅ how a tensile test works and what the abbreviations Rm, Re, A, and Z mean, ✅ how hardness is measured using the Brinell, Vickers, and Rockwell hardness methods, ✅ what the Charpy test shows and why steel becomes brittle in the cold, ✅ how to assess weldability and hardenability (Jominy test), ✅ what the difference is between good machinability and a disaster for a milling machine, ✅ and which physical properties (density, conductivity, thermal expansion, and thermal resistance) are worth knowing! 🎬 If you're interested in materials, technology, or just like to know "what things are made of" – subscribe to Stalowe Fakty and stay with us for longer! 📲 Also check out our social media: 👉 Instagram: @stalowefakty 👉 Facebook: Stalowe Fakty
