Revised Footnotes and added Footnotes 4, 6 and 7.1. SCOPE In 1941, the SAE Iron and Steel Division in collaboration with

6、 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

7、 fixed ranges and limits without tolerances formerly provided for carbon and other elements in SAE steels (reference SAE J408). ISTC Division 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 s

8、olicit 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 producti

9、on 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 prod

10、uction 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

11、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 vari

12、ations 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. SAE J404 Revised JAN2009 Page 2 of 62.

40、sed JAN2009 Page 6 of 6DISCLAIMERPrevious versions of this Standard have sometimes listed different chemistry ranges for the same steel grade depending on the product form. These differences in chemistry ranges between different product forms reflected steelmaking capability at the time. As an outco

41、me of last SAE industry wide grade steel survey it was agreed that chemistry ranges for various product forms should be harmonized into one chemistry for each grade. This change simplifies the steel grade tables in the standard and better represents the current improved chemistry capability of steel

42、 producers In some cases, however this has resulted in more restrictive chemistry ranges for some product forms e.g. sheet products, which traditionally have permitted wider tolerances. As a consequence, some products which conformed to the previous standards are now out of compliance with this new

43、current version. To address this issue, Division 1 Technical Committee agreed that until the next planned review of this standard, both the past standard (SAE J403-Nov01 or SAE J404-Nov01) and the current Standard shall apply. Thus any material which conforms to EITHER the Past or the Current versions shall be considered to be in compliance with the standard. This deviation shall apply only until the next revision of the standard is published - expected to be issued no later than 2014.
