India Made 87% of This Bridge's Steel — And Nobody Told You | The TISCROM Story TC156

In 1936, when work on Howrah Bridge began, the plan was simple — all the steel would come from England. Then World War 2 happened. Britain's steel went into battleships and tanks. The bridge was left standing half-finished. That's when an Indian company did something that should have been written into history — but wasn't. Tata Steel developed a brand-new high-tensile alloy — TISCROM. Made in the blast furnaces of Jamshedpur, from Indian iron ore, by Indian workers. The backbone of Howrah Bridge — 87% of its steel — was Indian. No nuts. No bolts. Only rivets. Thousands of Indian workers hand-riveted every single joint — in the middle of a World War, under the threat of bombing. 83 years later, that bridge still carries over 1 lakh vehicles every single day. This is the story of Howrah Bridge — and more than that, it's the story of Jamsetji Tata's dream: that India would make its own steel. 🎙️ The CODE — Episode 156 Host: Rishabh Aggarwal Chapters: 00:00 — India's Most Photographed Structure 01:11 — The Hidden Story Behind the Bridge 02:00 — Why Kolkata Needed a Bridge 02:46 — 80 Years of Delays & the Hooghly Problem 03:30 — The Cantilever Design Solution 04:15 — WW2 & the Steel Crisis 05:53 — TISCROM: Tata Steel Steps In 08:02 — Rivets, Caissons & the Overnight "Earthquake" 10:17 — The Bridge Opens in 1943 11:50 — Tata Steel's Legacy Today 12:29 — The Lesson: Reject "Good Enough" 13:50 — Final Thoughts & Next Episode Tell us in the comments — which joint in your own project is only "good enough" right now?
