In our reinforced concrete episode, we learnt that concrete began as a plant pot. Today we discuss the less humble origins of steel, who's inventor also developed patents for sugar extraction and reducing seasickness on passenger ships.

We also learn about steel's 'Achilles heels'; we discuss an extraordinary example of fatigue, consider the environmental impact of corrosion protection, and Janet tries to restrain Ellie from yabbering on about her passion - buckling.

Enjoy learning even more about steel, and please reach out to us with any questions or topics you would like us to discuss! Also, we're now on TikTok! https://vm.tiktok.com/ZGdFftpC7/
