Steel:

Steel Making Pittsburgh an Industrial Giant

Why Steel?:

Learning Target:

Learning Target I can explain why steel was important to the industrialization of America. I can identify the qualities of steel that make it a superior metal to iron.

Early Problems:

Early Problems Very costly! Inefficient process Very difficult to produce Why though? Difficult to make! It is a chemical mixture Must be precise to produce good steel Good methods needed! It does not yet exist! This onerous process yielded paltry earnings on account of archaic modus operandi in the field of metallurgy. ? My friend was just trying to say that they needed a better method to create steel.

New Process Discovered!:

New Process Discovered! Called the Bessemer Process Discovered by two separate men Henry Bessemer William Kelly Made steel more profitable! Cost less to produce Took less time Higher quality The steel industry was off and running!
