a hard metal that people use to make many different products. Car bodies, bridges, building frames, and containers are just a few of the things made from steel. (1) But steel is better than iron in many ways. Steel is stronger but lighter than iron. Steel also lasts longer than iron....
Iron and steel serve different purposes. Let’s take a more in-depth look at the difference between iron and steel. #1 Strength and Weight Steel is unmatched in strength. It is stronger than iron and has a higher level of density. Due to this strength and versatility, steel is very popul...
Steel isstronger but lighter than iron. Steel also lastslonger than iron.T hen they add carbon to the liquid iron.T hey may also add other materials to make different types of steel. For example, steel with added chromium(铬) is called stainless stee1. It will not rust(生锈) or stain...

Finally, workers use machines to cool the liquid steel into bars or long sheets. 【3】 People made the first steel as early as 1400 BC. Ancient people heated iron inside a pile of burning charcoal(木炭). 【4】. The result was not the same as modern steel, but it was stronger than ...
Carbon steel, on the other hand, has far lower chromium levels, and is instead a carbon-iron alloy with only a few other materials, if any, as part of its makeup. As a result, it can be referred to as ‘low-alloy’ steel. Both stainless steel and carbon steel feature this basic ...
All stainless steel metals are a type of steel. That means their chemical composition contains iron. In most cases, stainless steel varieties with iron in
As its name suggests, however, cast iron is meant solely to be cast;it cannot be forged. ... On the other hand, steel can be either cast or forged into the desired shape. It can also be welded and is generally stronger than cast iron, making it a suitable choice for high-pressure,...
Strength - Stainless steel is 2-3 time stronger than aluminum pipe. The tensile strength of 304L stainless is 79,000psi (316 is 80,000psi), compared to 25-40,000psi for aluminum pipe (depending on grade used). Plus, steel is 'strain rate sensitive', many aluminum structural grades ar...
