Material characteristics R steel is a German die-casting mold material with extremely high high-temperature strength and good crack resistance. It has high thermal tensile strength, good tempering resistance and hardenability, and small heat treatment deformation. Calcium treatment gives the steel excellent mechanical properties.
Chemical composition
The chemical composition (mass fraction) of the steel: 3,.,3.,.,<.
Refer to the corresponding grades
German standard material number .3R, German standard grade R, Austrian standard grade.
