Songshun Quality Assured Scm440 Steel Core Applications In Key Areas - China

In the field of engineering machinery, SCM440 steel is mainly used in three types of key components: hydraulic pump gears need to withstand contact stress exceeding 2000MPa; excavator slewing gear rings need to resist impact loads; crane winch shafts simultaneously withstand bending and torsion composite stresses.

Sany Heavy Industry's technical specifications require that the fatigue limit of these components be no less than 550MPa under working conditions of -25℃ to 120℃, and SCM440 fully meets this stringent standard.

The automotive transmission system is the "main battlefield" of SCM440 steel.

Nissan's test data shows that the main reducer gear made of SCM440 steel has a tooth surface contact strength of 1600MPa and a bending fatigue limit of over 850MPa.

Through a special carburizing and quenching process, the surface hardness can be increased to HRC58-62, while the core still maintains the toughness of HRC35-40 - This "hard outside and tough inside" characteristic is the ideal state of gear materials.
