(PDF) NEW Fe-C-Mn-Si-Cr BEARING ALLOY:TEMPERING

Based on the same idea as 300M steel regarding SAE/AISI 4340 steel, a new Fe-C-Mn-Si-Cr bearing alloy [Show full abstract] (AISI 52100 steel, modified with 1.74% Si and 0.96%Mn) was developed. 4340M / 300M VAR Cr-Ni-Mo-V Aircraft Quality Alloy Steel

  • DescriptionApplicationsSpecificationsAvailable FormsEssentially 300M is a modified AISI 4340 steel with silicon, vanadium and slightly more carbon and molybdenum. 300M has a very good combination of strength at 19302100 MPa (280-305 ksi), toughness, fatigue strength and good ductility. It is a through hardening alloy.

AISI 434 , 434 stainless steel, AISI 434 steel - Steel AISI 434 stainless steel is a modification of Type 430, one of the most widely used of the"non-hardenable" ferritic stainless steels. The addition of molybdenum increases this alloy's corrosion resistance and its attack from many deicing chemicals. AISI 434 stainless steel also provides good heat and oxidation resistance up to 1500°F (816°C) as well as good mechanical properties.

    CLASIFICACIÓN DE LOS ACEROS SEGÚN LA NORMA AISI

    Nov 01, 2013 · NORMA AISI-SAE Clasificación de los aceros según la norma AISI-SAE La norma AISI/SAE (también conocida por SAE-AISI) es una clasificación de aceros y aleaciones de materiales no ferrosos. Es la más común en los Estados Unidos. AISI es el acrónimo en inglés de American Iron and Exporters and Importers of Nickel AlloysFeb 02, 2018 · RENINE METALLOYS is a specialist manufacturer and Distributor of internationally procured materials from various reputed MILLS. Nickel Alloy and Special Metal which includes Sheets, Plates, Bars, Seamless Pipes, ERW Pipes and In-house manufacturing facility for Flanges, Fasteners, Pipe Line Equipments. Hard alloys - Acos Villares S.A.The material thus machined was a SAE-4340 steel which had been hardened and tempered to a hardness of 300 HB. The life of the tool as a function of the cutting speed is shown in FIG. 17, for a wear width I L =0.6 mm. The tools made from the new steels have a substantially longer life than the tools made of steel without niobium.
