DIN 1651 Grade 60SPb20 turned and quenched and tempered
DIN 1651 Grade 60SPb20 turned and quenched and tempered introduction
The fully killed machining steel 60 SPb 20 is used for mass parts of highest strength, especially for lower toughness demands cross-sectional. Its better machinable because of the Pb addition.
Application in the automotive engineering, toolbuilding, apparatus engineering (screws, nuts, smal parts).
Equivalent material: DIN 1.0758, DIN 60 SPb 20, DIN 60SPb22, EN 60SPb20, EN 1.0758
