Steels that contain specified amounts of alloying elements -- other than carbon and the commonly accepted amounts of manganese, copper, silicon, sulfur, and phosphorus -- are known as alloy steels.

Compare popular steel alloys used in modern engineering. Learn where A36, 4140, 304 stainless, A572 Grade 50, and 2205 duplex ...

Alloys are not just random combinations of elements; they are precisely engineered to enhance specific properties, such as strength, corrosion resistance, ductility, and conductivity. 1, 2 For example ...

In its purest form, iron is neither exceptionally strong nor hard - in fact, a block of pure iron could be cut with a knife. The addition of carbon and the removal of oxygen are what give iron-based ...
