Typical tensile strength ranges from 114,000 PSI (Annealed Condition) up to 156,000 PSI (Pre-Hard, Quench and Tempered Condition). AISI 4140 and 4150 steels offer a high resistance to fatigue, improved toughness, impact resistance, and torsional strength. Not all AISI 4140 and 4150 materials are made to the same standards. AISI 1045 1.1191 C45 S45C - Xingsheng Special steelRemark:Water Quench at 820 o C -850 o C or oil quench at 830 °C-860°C and Tempered Between 540 °C 680 °C 5.Forging. Heat AISI 1045 with two steps,first heat the temperature to 750 o C 800 o C ,hold for suitable time,then heat the temperature up to 1100 o C 1200 o C,hold enough time for the steel to be thoroughly heated.Minimum forging temperature 850°C,so dont forge below
AISI 1045 steel is high-quality medium-carbon steel with high strength. It also can be called JIS S45C and DIN C45 steel. It is usually used in normalized condition because of its bad hardenability. It needs to be quenching and tempering treatment to get higher mechanical performance. AISI 4340 Quenched And Tempered - Nickel Chromium We have 60 suppliers for AISI 4340 Quenched And Tempered .

Oct 01, 2013 · After performing the experiments, in the first stage, the effects of tempering temperature and time on hardness drop of water-quenched AISI 1045 steel were investigated. In the second stage, an artificial neural network (ANN) model was developed to predict the hardness drop of the water-quenched and tempered AISI 1045 steel specimens, as a Fatigue Performance As Measured By Fatigue Strength Nov 12, 2013 · AISI has also evaluated a number of quenched and tempered steels over a wide hardness range of 222-584 BHN. Included were carbon steels, low alloy steels, and spring steels. For these steels, the direct use of strain-life data offers a means of comparing long-life fatigue performance as a function of hardness. Heat Treatment of Plain Carbon and LowAlloy Steels procedures for AISI 1045 and/or AISI 4140 steels. Conduct mechanical tests on specimens of 1045 and/or 4140 steels which have been subjected to four dierent heat treatment procedures:1. Asreceived (normalized); 2. Austenitized and slowcooled (annealed); 3. Austenitized and waterquenched; and 4. Austenitized, waterquenched, and
quenched (850°C:30 min) in oil and tempered at 100, 200, 250, 300, 400, 500 and 650°C, for 2 and 48 h, respectively. The results obtained are listed in Tables 2 and 3, in which the data for the as-quenched condition are included for comparison. As expected, the mechani-cal behaviour of AISI Mixed-mode fracture behaviors of AISI 1045 and AISI 5140 Mar 01, 2020 · The AISI 1045 and AISI 5140 steels were forged between 850 and 1150 and subsequently air cooled to room temperature. Then the AISI 1045 steel was heated to 860 and quenched in salt water, followed by tempering at 600 while the AISI 5140 steel was heated to 850 and quenched in oil, followed by tempering at 590. Normalized SAE-AISI 4130 vs. Quenched And Tempered SAE May 30, 2020 · Both normalized SAE-AISI 4130 and quenched and tempered SAE-AISI 4130 are variants of the same material. They share alloy composition and many physical properties, but develop different mechanical properties as a result of different processing. For each property being compared, the top bar is normalized SAE-AISI 4130 and the bottom bar is
QUENCHED AND TEMPERED STEELS Quenched and tempered steels are unalloyed and alloyed machine manufacture steels featuring high saturation at a certain tensile strength after quenching and tempering process, which are suitable for hardening in terms of What is quenched and tempered steel? - ShapeCUTHaving a thorough understanding of how quenched and tempered steel is produced and its material properties helps define how best to cut, bend and work the steel. At ShapeCUT, we have 5,000+ tonnes of steel in stock, including quench and tempered plate, and the technical know-how and experience to craft it into any form imaginable. temper air quenched for AISI 4140 and for AISI 1045 it was temper, air quenched for AISI 4140 and for AISI 1045 it was 40 minutes tempered, oil quenched. Tempering time decreases the hardness of the material as seen on the graph. Thus, the hardness of the original material is still less. Specific hardness is often altered due to tempering.
