⚙️ Metal-e Allergy to Metal-e Energy ⚡

When Metallurgy becomes a life‑changing story!

🚀 Metallurgy for Non‑Metallurgists 🚀

🎯 Why is this website special?

Do you get a headache when you hear the word “Metallurgy”? Do you feel scared or bored? Do you think it is a very difficult, boring subject?
Then this website is made especially for you! 🌟

I have worked for 20 years in the Indian Steel Industry. In the beginning, I tried to run away from Metallurgy. But slowly I realised how this subject can change a person’s life and career. That is when my “Metal Allergy” slowly turned into “Metal Energy!”

I have written this book for the Next Generation – so that you do not waste time making the same mistakes that I made. The challenges, problems and struggles in my career can become a shortcut for you to skip those pains.

This is not a normal textbook. It is an experience‑based guidebook.


At the end of this journey, I remember a powerful promise from the Bengali poet Sukanta Bhattacharya:

“চলে যাব— তবু আজ যতক্ষণ দেহে আছে প্রাণ
প্রাণপণে পৃথিবীর সরাব জঞ্জাল,
এ বিশ্বকে এ শিশুর বাসযোগ্য ক’রে যাব আমি
নবজাতকের কাছে এ আমার দৃঢ় অঙ্গীকার।”

I will die one day, but as long as there is life in my body,
I will give my full effort to reduce the problems of this world.
I will try to make this world a better place for the next generation.
This is my strong promise to every newborn child.


🎯This book and this website
👉 are my small effort towards that promise.

If even one young engineer, after reading this, stops being afraid of Metallurgy and learns to turn “Metal Allergy” into “Metal Energy”, then this journey is successful. 💫
