Why steel is stronger than iron? #Steel #Iron #Metallurgy #MechanicalEngineering #MaterialScience

Why is steel used in bridges, buildings, tools, and machines instead of pure iron? The answer lies at the atomic level. Pure iron has atoms that move easily, making it soft and weak under load. When a small amount of carbon is added, it forms steel. Carbon atoms block the movement of iron atoms, increasing strength and hardness. Steel can also be heat treated to form strong microstructures like martensite, which is not possible with pure iron. That’s why steel offers higher strength, durability, and safety in real-world engineering applications. #Steel #Iron #Metallurgy #MechanicalEngineering #MaterialScience #EngineeringBasics
