38CrMoAl Alloy Structure Steel Round Bar DIN 1.8509 41CrAlMo7-10 Forged Rod 650mm

38CrMoAl Alloy Structure Steel (Nitride Steel) Round Bar DIN 1.8509 41CrAlMo7-10 Forged Steel Rod

38CrMoAl is an alloy structural steel characterized by high aluminum composition, which is generally used after quenching and nitriding.After nitriding, 38CrMoAl has high surface hardness, wear resistance and fatigue strength, and has good heat resistance and corrosion.

The characteristic of 38CrMoAl nitriding is that the speed is fast and the depth of nitriding layer can be obtained. However, the brittleness of the nitriding layer is relatively large, so it is not suitable for making parts that bear great impact.

HEAT TREATMENT

TRIDING TREATMENT

The process flow of nitriding parts is generally: forging → normalizing (annealing) → rough machining → tempering and tempering → finishing machining → de-stress → fine grinding → nitriding → fine grinding → assembly.

The purpose of 38CrMoAl nitriding treatment is mainly for wear resistance.After nitriding, its hardness is as high as HV800, the hardened layer can reach 0.30mm ~ 0.5mm.

APPLICATION

38CrMoAl is mainly used in the manufacture of parts with precise size, requiring high wear resistance and fatigue strength, and not subjected to large impact load, such as cylinder liner, bottom sleeve, gear, bolts, shaft and rotor, etc.

In addition, because Al and Cr elements can form a dense passivation film on the surface of steel, so 38CrMoAl is also a kind of seawater corrosion resistant steel.Its seamless steel pipe is the most ideal pipeline and processing material for transporting water, oil and gas and seawater containing medium in coastal power plants, coastal oil fields, coastal natural gas and petrochemical plants.
