This is because the AISI was not the author of the specifications. You will see steel quotes and certifications today that make reference to both AISI and SEA. Often, these are not precisely differentiated. For instance, you will see refernces to 317l stainless steel, AISI 317 or SAE 317.

It is possible that AISI grades are quoted as SAE grades and it is often that AISI/SAE have the same steel identification number.

As mentioned, amount of sulfur may be increased from 0.06% to 0.15% to enhance the machinability of group A, M, T, H and D steels. b Present in various carbon ranges. c Presence of free graphite in the microstructure. AISI 4130 Pipes 4130 Tubing - 4130 Tube - SAE AISI 4130AISI 4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. We stocks all AISI 4130 Pipes, 4130 Tubing, 4130 Flanges, 4130 Pipes Fittings, 4130 Elbow etc. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint.
