4340 This nickel-chromium-molybdenum alloy steel is a very high strength steel. It is sought after for its toughness and for being used as a steel that will be highly stressed. It is used in a variety of industries for different applications including the automotive, aerospace, and tooling industries. Chemical Properties AISI 4340 1.6511 36CrNiMo4 SNCM439 - Waldun SteelAISI 4340 steel Manufacturer and Exporter,supplied with round,square,flat,block,and shaft etc.AISI 4340 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 resistance and atmospheric corrosion resistance.AISI 4340 is

You can use 4140 as a close reference for 4145H and I think you can find 4140 anywhere. 4145H will have slightly higher strength and lower ductility for final properties if both go through same heat treatment.
AISI 4340 Fasteners - Boltport FastenersAISI 4340 is a chromium-molybdenum alloy steel with high strength properties, used for manufacturing wide range of fasteners across ASTM and ISO bolting standards. AISI 4340 alloy steel fasteners are manufactured using as rolled bar stock followed by quench and tempering to achieve full grade strength as required to A320 L43, F568 Grade Class
AISI 4340 Steel, oil quenched 855°C (1570°F), 230°C (450°F AISI 4340 has a favorable response to heat treatment (usually oil quenching followed by tempering) and exhibits a good combination of ductility and strength when treated thusly. Uses include piston pins, bearings, ordnance, gears, dies, and pressure vessels.

AISI 4340 is stocked in the heat treated and stress-relieved condition at approximately 150,000 psi (1034 N/mm2) and in the annealed condition at HB 235 max. Typical Applications High strength machine parts, heavy-duty shafting, high tensile bolts and studs, gears, axle shafts, crankshafts, boring bars and down-hole drilling components Evaluation of toughness in AISI 4340 alloy steel (untempered) AISI 4340 steel has shown that compared to conventional austenitizing at 870~ increasing the austenitizing temperature to 1200~ can raise the plane strain fracture toughness (Kic) by a factor of two (without reduction in yield strength). However, concurrent with this improvement in Kic there is aneFunda:Properties of Alloy Steel Alloy Steel AISI 4340Tensile Strength (MPa) 1279.0 :Yield Strength (MPa) 861.8 :Elongation (%) 12.2 :Reduction in Area (%) 36.3 :25:oil quenched, fine grained, tempered at 205°C :Tensile Strength (MPa) 1875 :Yield Strength (MPa) 1675 :Elongation (%) 10 :Reduction in Area (%) 38 :25:oil quenched, fine grained, tempered at 315°C :Tensile Strength (MPa
