Steel is essentially the inspiration of modern industrial economies, and it is employed in many various fashionable manufacturing capacities. As such, it’s important to understand how two of the most important worldwide specs, JIS and the AISI standards match up in opposition to one another.

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.

  • AISI 4340 can be one kind of nickel chromium molybdenum steels.
  • is a medium carbon, low alloy steel identified for its toughness and strength in relatively giant sections.
  • The 4340 steel has good shock and impact resistance as well as wear and abrasion resistance within the hardened situation.
  • 4340 alloy steel is mostly equipped hardened and tempered within the tensile range of 930 – 1080 Mpa.

AISI 4340 steel properties provide good ductility in the annealed situation, allowing it to be bent or shaped. Fusion and resistance welding is also possible with our 4340 alloy steel. ASTM 4340 materials is commonly utilized where other alloy steels don’t have the hardenability to offer the strength required. AISI 4340 alloy steel can be machined by all customary methods. Similar to alloy grade AISI 4130 chrome moly alloy steel however with a slightly higher carbon content.

Type S— is a extremely alloyed austenitic stainless steel used for top temperature utility. The excessive chromium and nickel content give the steel wonderful oxidation resistance as well as high power at high temperature. This grade can be very ductile, and has good weldability enabling its widespread utilization in many purposes. Stainless steels are also included within the AISI steel specs range.

In this way, it’s attainable to know a bit about the composition of the steel, simply from its name. For instance, 1040 AISI steel is carbon alloy steel that accommodates 0.forty weight % Carbon alloy. Before this can be undertaken, it must be recognized that two precisely equivalent steel specifications do not exist. The easy realization that the 2 totally different standards are maintained by two separate organizations signifies that they may diverge in the future, or have diverged at some minor inflection prior to now.

We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.

Characteristics of Stainless Steel Sheet and Plate:
High corrosion resistance
High strength
High toughness and impact resistance
Temperature resistance
High workability, including machining, stamping, fabricating and welding
Smooth surface finish that can be easily clean

The early 1940’s witnessed the development of a coding system for the classification of different types of steels. Designers, heat treaters, draftsmen, and engineers had been capable of obtain specific info on the forms of steel together with its grades. The coding system is known for its efficient classification of steels because it makes use of the standards from the American Iron and Steel Institute (A.I.S.I.) and the Society of Automotive Engineers (S.A.E.).

Since the American Iron and Steel Institute ceased writing materials specifications, the relationship between AISI and grade designations has been discontinued. From point of edition of the 1995 Iron and Steel Society Strip Steel Manual, the 4-digit designations are referred to solely as SAE Designations.
