The material we know as "steel" is an alloy of iron that contains less carbon than this: almost always less than 2%, and usually about 0.4%. Changing the amount of carbon greatly influences the properties of the material. More ductile 'wrought' iron could be made at the start of the Industrial Revolution, but only by a slow, small-scale and ...

Iron and steel consist of grains made of different kinds of iron and carbon, some of which are hard, while others are soft. When the harder kinds predominate, you get a hard and brittle material; when there are more softer kinds in between, the material can bend and flex so you can work and shape it more easily.
