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. Aço SAE 4340 Propriedades MecânicasTranslate this pageAISI, SAE ou ABNT 4340? Esse aço as vezes também é chamado de AISI 4340. AISI e SAE são entidades americanas que tem como objetivo a classificação dos materiais. Na prática não há diferença em uso de um nome ou de outro, com exceção da ABNT que não utiliza essa nomenclatura.

Due to E-4340's high alloy content it obtains a uniformed hardness by heat treatment. The high fatigue strength makes E4340 ideal for highly stress parts as it maintains it's strength and hardness at elevated temperatures.
