SURFACE VEHICLE 400 Commonwealth Drive, Warrendale, PA 15096-0001 STANDARD Submitted for recognition as an American National Standard J404 REV. JUN2000 Issued 1911-06 Revised 2000-06 Superseding J404 APR1994 Chemical Compositions of SAE Alloy Steels 1. Scope—In 1941, the SAE Iron and Steel Division in collaboration with the American Iron and Steel Institute (AISI) made a major change in the method of expressing composition ranges for the SAE steels. The plan, as now applied, is based in general on narrower ladle analysis ranges plus certain product (check) analysis allowances on individual samples, in place of the fixed ranges and limits without tolerances formerly provided for carbon and other elements in SAE steels (reference SAE J408). ISTC Divison 1 has developed a procedure which allows for the maintenance of the grade list in this SAE Standard. This will involve conducting an industry-wide survey to solicit input. This survey will be conducted at a frequency deemed necessary by the technical committee. Criteria have been established for the addition to or deletion of grades from the grade table. A new grade will be considered if it meets standard SAE grade ranges, has a minimum usage or production of 225 tonnes/year (250 tons/year), and has the endorsement of at least two users or producers. New steel compositions will still be considered as Potential Standard (PS) steels, based on the guidelines provided in SAE J1081, until such time as production of the new steel achieves a level of production or usage qualifying it for consideration as a standard steel. The deletion of a grade from the grade table will be by consensus based on the grade survey results. Deleted grades will be archived in SAE J1249 for future reference. The compositions in this document may apply to open hearth and basic oxygen, or electric furnace steels. Grades shown in Table 1 with prefix letter E are normally made by the electric furnace process with maximum limits of 0.025% phosphorus and 0.025% sulfur. The nominal chemical limits or ranges in the compositions given in Table 1 are subject to standard variations in check analysis given in SAE J409. Since AISI is no longer issuing steel grade designations, all grades listed in this document are SAE grades. Table 1 is applicable to billets, blooms, slabs, plates, wire rods, and hot-rolled and cold-finished bars. SAE J404 is not applicable to the following product forms: a. Structural shapes—Not normally furnished to alloy chemistries b. Sheet and strip, hot-rolled and cold-rolled—Refer to ASTM A 506 and A 507 c. Seamless and welded mechanical tubing—Refer to ASTM A 513 and A 519 SAE J404 Revised JUN2000 -2- 2.

For standard variations in composition limits, see Table 4 of SAE J409. Small quantities of certain elements which are not specified or required may be found in alloy steels. These elements are to be considered as incidental and are acceptable to the following maximum amounts: copper to 0.35%, nickel to 0.25%, chromium to 0.20%, and molybdenum to 0.06%. Lead - Alloy steels can be produced with a lead additon of 0.15 to 0.35% to improve machinability. Such steels are identified by inserting the letter “L” between the second and third numerals of the grade number, for example, 51L40. The analysis of the following elements shall be reported regardless of whether they are specified: Aluminum, Titanium, Niobium (Columbium), Vanadium. If the analysis of any of these elements is less than 0.008%, it may be reported as <0.008%. 2. Electric furnace steel. 3. Boron content is 0.0005 to 0.003%.
