A 4-digit number is normally given to the AISI alloy steels and carbon steels. The alloying component within the AISI specification is indicated by the primary two digits and the amount of carbon is indicated by the final two digits.
The stainless steels are provided with three digit numbers beginning with 2, 3, 4, or 5. The 300 series austenitic stainless grades and the 400 sequence martensitic grades are the favored stainless steel specs.
Are AISI and SAE the same?
Grading of AISI Materials A basic four-digit system is used by the SAE system to designate the chemical composition of alloy steels and carbon steels. There is a possibility that AISI grades are quoted as SAE grades and very often the same steel identification number is present in AISI/SAE standards.

What is AISI material?
In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels. The alloy number is simply a general classifier, whereas it is the specification itself that narrows down the steel to a very specific standard.
- AISI 4340 is also one kind of nickel chromium molybdenum steels.
- is a medium carbon, low alloy steel identified for its toughness and power in comparatively large sections.
- The 4340 steel has good shock and impression resistance as well as put on and abrasion resistance within the hardened condition.
- 4340 alloy steel is usually equipped hardened and tempered within the tensile vary of 930 – 1080 Mpa.

Type S— is a highly alloyed austenitic chrome steel used for prime temperature software. The high chromium and nickel content material give the steel glorious oxidation resistance as well as high strength at high temperature. This grade can also be very ductile, and has good weldability enabling its widespread utilization in many purposes. Stainless steels are additionally included in the AISI steel specifications vary.

In this way, it’s possible to know a bit in regards to the composition of the steel, merely from its name. For example, 1040 AISI steel is carbon alloy steel that incorporates 0.forty weight % Carbon alloy. Before this can be undertaken, it must be acknowledged that two precisely equal steel specifications do not exist. The simple realization that the 2 totally different requirements are maintained by two separate organizations means that they might diverge sooner or later, or have diverged at some minor inflection up to now.

The early 1940’s witnessed the development of a coding system for the classification of several types of steels. Designers, heat treaters, draftsmen, and engineers have been able to acquire specific info on the types of steel along with its grades. The coding system is understood for its efficient classification of steels because it uses the requirements from the American Iron and Steel Institute (A.I.S.I.) and the Society of Automotive Engineers (S.A.E.).

The tensile energy of the 4340 steel material core is normally not affected because the nitriding temperature range is mostly beneath the unique tempering temperature employed. The JIS number roughly follows the AISI format wherever possible. Additionally the particular function steels such as chromium or silicon steels, which might be the AISI 5000/6000/9000 sequence steels, are usually designated as SUP/SUJ/SUM in the JIS specification. An additional letter is typically added between the second and third digits of the code teams corresponding to 11L41, 12L14 or 50B40. The letter L indicates the addition of lead (between 0.15% and 0.35%) to enhance the machinability of the steel.
