EN 10277-3 Grade 10SPb20 cold drawn introduction
The free cutting case hardening steel 10SPb020 shows uniform properties of the cross-section and within the melt as well as enhanced machinability by Pb- and S-addition. Application for thin-walled case hardened parts in car industry, apparatus, equipment and machine engineering. As a bright steel product it is used in the form of bars, bright, straight, in various conditions (see DIN EN 10277 : 1999-10).
