40CrNi3MoA属于航空用高纯洁度合金结构钢棒，简称钢棒，执行标准：GJB6487-2008.

40CrNi3MoA主要用于制造强度高、塑性好的重要零部件，氮化处置后制造特别功能需求的重要零件，如轴类、齿轮、紧固件等。 40CrNi3MoA冶炼方法：钢采用电弧炉+电渣重熔或感应炉+电渣重熔方法冶炼，经双方协商，并在合同中注明，也可采用其他满足本标准规范要求的冶炼方法。

40CrNi3MoA is an aviation-grade high-purity alloy structural steel bar, commonly referred to as a steel bar, and it complies with the standard GJB6487-2008. 40CrNi3MoA is primarily used for manufacturing important components that require high strength and good plasticity. After nitriding treatment, it is employed to produce critical parts with special functional requirements, such as shafts, gears, and fasteners. The smelting method for 40CrNi3MoA: The steel is smelted using an electric arc furnace plus electroslag remelting or an induction furnace plus electroslag remelting. With mutual agreement and noting in the contract, other smelting methods that meet the requirements of this standard can also be adopted. ——————————
