SAE4340, same as UNS G43400. Tensile strength σb ≥980(100) Yield strength σs ≥835(85), used to manufacture important parts with high strength and good plasticity. After nitriding treatment, make important parts with special functional requirements, such as shafts, gears, and gears. Firmware etc. Delivery steel flat 50x10 S690QL in heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment.

NM400 wear resistant steel plate has a very high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates; it can improve the wear resistance of mechanical related parts; therefore improve the service life of machinery; reduce production costs. The surface hardness of the product steel flat 50x10 S690QL is usually Reached 360 - 450HB. NM400 wear resistant steel plate is used for processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.

A small amount of Nb is sufficient to obtain excellent comprehensive properties of steel flat 50x10 S690QL etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.
