Blocks of Steel are made of 9 steel arranged in a crafting table. They, like steel is compared to iron and steel bars are compared to iron bars, have a lighter color than blocks of iron but have the same texture. Blocks of steel have the same mining speed as if it was diamond that was used to make it. Blocks of steel can have purposes on building buildings and houses. Like the other blocks made out of valuables, they are not flammable. Like blocks of iron, they can be used to make beacons emit light.
