steel (SAE 4140), and by 7% to 11% compared to a quenched and tempered carbon steel (SAE 1050). In addition, the micro-alloy grades met or exceeded the fatigue strength of the original materials for the applications studied and had better machinability characteristics. Detailed dynamic load SAE AISI 4140 Steel Properties, Material Heat Treatment Dec 14, 2019 · SAE AISI 4140 Alloy Steel. SAE 4140 (AISI 4140 steel) is a Cr-Mo series (Chrome molybdenum series) low alloy steel, this material has high strength and hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperature. 4140 Steel Uses. AISI SAE 4140 alloy steel can be made into round steel bar, flat & square steel AISI 4140 Chrome-Molybdenum High Tensile SteelAISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of the AISI 4140 include superior toughness, good 4340 Steel AISI 4340 1.6511 36CrNiMo4 SNCM439 WALDUN is a good Chinese AISI 4340 steel Manufacturer and Exporter.You can get supplied with round,square,flat,block,and shaft etc from WALDUN.. AISI 4340 steel is defined as a heat treatable and low alloy steel which has 0.8% Cr, 0.2% Mo and 1.8% Ni as strengthening alloy elements.Compared with AISI 4140,it has higher strength and toughness,also it has very good fatigue resistance, wear Fabricating and Repairing 4130 and 4140 Steels in Heavy Sep 22, 2018 · AISI/SAE 4130 and 4140 specifications refer to a chemical composition range only, as opposed to both a chemical composition and mechanical property ranges. Both 4130 and 4140 have carbon, chromium (0.80 percent to 1.15 percent) and molybdenum (0.15 percent to 0.25 percent) as primary alloying elements. AISI 4140 Alloy SteelProduct introduction. AISI SAE 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components, like axles, shafts, bolts, gears and other applications. Similar to alloy grade AISI 4130 chrome moly alloy steel but with a SAE 4140 Alloy Round Bar SCM440 Round Bar ssroundbarAISI 4140 machines well in the supply condition of 18-22HRc.4140 is a 1% chromium molybdenum medium hardenability general purpose high tensile steel generally supplied hardened and tempered in the tensile range of 850 1000 Mpa (condition T).4140 is now available with improved machinability, which greatly increases feeds and/or Offer 4140 Pump Shaft Tolerance, List of 4140 Pump Shaft sae 4140 steel equivalent. 4140 steel jis equivalent. 4140 steel grade equivalent. 4140 annealed steel round bar. 4140 annealed steel bar steel bar for crankshaft. Auto steel steel bar for crankshaft Crankshaft is a shaft driven by a crank mechanism consisting of a series of cranks and crankpins to which the connecting rods of an engine are Eagle Crankshaft 545442526385; Forged 4140 4.250" Apr 27, 2021 · Material:Forged 4140 Steel. Engine:396-454 BBC. The Eagle ESP Forged 4340 Steel Crankshafts feature exceptional strength and unsurpassed quality at a reasonable price and are the perfect choice for high-performance applications. AISI 4140 Alloy Steel - Quality Products & Best PricesAISI 4140 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling in the furnace. Tempering. AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has a lower tempering temperature. AISI SAE 4140 Steel - JIS SCM440 - DIN 1.7225 - Songshun SteelAISI 4140 Steel Round Bar Sheet Plate, JIS SCM440, DIN 1.7225. AISI 4140 alloy steel round bar sheet plate has high fatigue strength and low notch sensitivity. Low-temperature impact toughness is also very high, no obvious temper brittleness. It is mainly used after quenching and tempering state.
