SAE J401-2000 pdf download Selection and Use of Steels
Scope-The SAE system of designating steels, described in SAE J402 classifies and numbers themaccording to chemical composition. In the case of the high-strength, low-alloy steels in SAE J1392 and J1442and the high-strength carbon and alloy die drawn steels in SAE J935, minimum mechanical propertyrequirements have been included in the designations. ln addition, hardenability data on most of the alloysteels and some of the carbon steels will be found in SAE J1268

Steel Designation–The steels so designated have been developed cooperatively by producers and usersand have been found through long experience to cover most of the wrought ferrous materials used inautomotive vehicles and related equipment. Because the SAE designations provide a convenient way forengineers to state briefly but clearly the chemical composition, and in some instances, some of the propertiesdesired, they are widely recognized and used throughout the United States and in many other countries.
it should be recognized that the many technological variations of the steel-making process, coupled with thediverse requirements of the numerous processes used in the manufacture of components, make it impossiblefor these brief SAE designations to completely describe any steel. A specification consists of a designationand whatever supplementary information may be necessary to describe the product desired. For this reasonthese designations should never be referred to as specifications, nor should they be used for purchasingunless accompanied by the necessary supplementary information to describe commercially the producidesired.
