9260 Steel is a metal made by alloying iron with carbon, and it is used in almost every industry thanks to its valuable mechanical properties. Its strength is paired with good workability and machinability, and it is relatively inexpensive to produce, which makes it a primary choice of material for most designers. The American Iron & Steel Institute (AISI) and the Society of Automotive Engineers (SAE) have made steel selection easier by naming different grades of steel with indexes that specify the alloying elements and general properties of the steel. This article will highlight 9260 steel, a high silicon alloy spring steel known for its outstanding working characteristics. By outlining the chemical composition, mechanical properties, and applications of 9260 steel, this article aims to help the reader decide whether 9260 steel is a good material choice for their project.

Physical Properties of 9260 Steel 9260 steel is given its four-digit name by the joint naming index created by the AISI and SAE. To learn more about this naming scheme, as well as the differences between steel grades, review our article on the types of steels.

The first digit designates the class of the steel alloy- that is, what the major alloying components are (besides carbon). For this steel, the “9” shows that this steel is of the silicon-manganese class of alloy steels. The second digit represents the percentage of these major elements; the “2” in 9260 steel, therefore, means this class is around 2% silicon/manganese. Finally, the last two digits represent the carbon percentage in the steel, in increments of 0.01%. Using this rule, 9260 steel is 0.60% carbon. The exact chemical composition of 9260 steel is much more specific, (seen below with tolerances), but its name gives a good idea as to its general makeup.

The specific elemental percentages of 9260 steel are:

0.56- 0.64% Carbon 0.75-1.0% Manganese
