AISI applauds retention of steel tariff Steelmakers’ association also endorses the 90-day “cooling down” time frame attached to tariffs on wider trade between the U.S. and China. “Chinese steel ...

AISI lists steel import reductions first in its 2025 priorities Steelmakers’ organization also urges tax policies that will encourage investments in new and upgraded capacity in the United States.

In present work, AISI 309 stainless steel studs were joined to AISI 1020 carbon steel sheets by arc stud welding technique. A range of welding currents and times were applied to investigate the effect ...

Results: To demonstrate the applicability of the method, the microstructure of a metastable austenitic steel in the two-phase region, where austenite and deformation-induced martensite coexist at room ...

Microstructure and fatigue strength of the roller-bearing steel 100Cr6 (SAE 52100) after two-step bainitisation and combined bainitic–martensitic heat treatment ...

For the grade 4130, the martensitic microstructure was about 750 HV 0.05 around the bond line, but in the SAE 1010, there were areas of lower hardness. In the hardness profiles of the 1010 and 4130 ...

For comparison, low strength stainless steel (AISI 304) tubes were also examined in the experiments. The microstructure of the welded joints was studied by optical microscopy. The hardness of the ...
