Types and properties of steel

Steel is an alloy of iron. It is formed by heating iron and combining carbon (0.1-1.7%) with it and minor amounts of other elements such sulfur, chromium, manganese, nickel, etc. Thousands of steel grades have been published, registered, or regulated around the world, each with its chemical composition, and special numbering systems have been devised in various countries to classify the vast number of alloys.

Puzzler: Most steel reinforcing bars manufactured in the U.S. exhibit a sharp yield plateau. Two exceptions, however, are bars that are quenched and tempered and bars that are coiled immediately after they are hot rolled. The coiled bars are later straightened by a fabricator. Both (1) quenched-and-tempered bars and (2) straightened bars have stress-strain curves that are initially linear, but yielding is gradual, producing what is described as a "round-house" curve. The reason for the round-house behavior is the same for both types of steel. Why do these two types of reinforcing steel exhibit gradual yielding rather than a sharp yield plateau even if the same steel exhibits a sharp yield plateau if it is not quenched and tempered or coiled?
