The SAE 4340 material properties are high tensile strength and high hardness. SAE 4340 equivalent grade is AISI 4340. AISI 4340 material comes under alloy steel of grades of steel. SAE 4340 has good machinability and hence it is used to make nuts, bolts, gears, shafts, crankshafts, etc. Buy AISI 4340 online from National Steel Industries. What is high tensile steel and is it worth the cost Jul 17, 2019 · The high tensile property is responsible for steels tension resistance, high yield and fatigue strengths at certain stress levels. The properties of high tensile steel are still present even when the material is exposed to elevated temperature levels, which makes it a very versatile material suitable for use in a myriad of situations.4340 (E4340) Alloy Steel, AISI 4340, Plate, Round Bar AQ AISI 4340 (E4340) alloy steel is a medium carbon, low alloy steel known for its toughness and strength. Machining is done typically in the annealed condition. 4340 steel properties offer good ductility in the annealed condition, allowing it to be bent or formed. Fusion and resistance welding is also possible with our 4340 steel from stock.
