SAE steel grades. The SAE steel grades system is a standard alloy numbering system (SAE J1086 - Numbering Metals and Alloys) for steel grades maintained by SAE International . 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.
Abstract In this study, AISI 303 steels are boronized by pack boring method at 1123, 1173 and 1223 K for 2, 4 and 6 h. The morphology of the boride layers formed on the steel surfaces was examined by optical microscope. The hardness values were measured by the micro-hardness tester and the phases formed on the layer were determined by XRD …
1.4305 – X8CrNiS18-9 (AISI 303) AISI 303 ist ein austenitischer, nichtrostender 18/10 Cr-Ni-Stahl, der mit Schwefel legiert ist, um eine Verbesserung der Zerspanung zu erreichen und damit eine Bearbeitung auf Automaten zu ermöglichen (Automatenstahl). Somit ist 1.4305 die Referenzgüte unter den Spanungsmaterialien.
Stainless Steel 303 is a free machining non-magnetic austenitic alloy specially designed for improved machinability while maintaining good mechanical and corrosion resistant properties. AISI 303 is cannot be hardened by heat treatment, but tensile and hardness can be increased by cold working with subsequent reduction in ductility.
X6CrNiCuS18-9-2. AISI/SAE. 303 Cu. UNS. S30330. Description. 1.4570 / AISI 304 Cu is an austenitic chromium-nickel stainless steel with copper contents. Special properties. Good corrosion resistance and good machinability due to the copper content.
