Application:
Steel grade 10kp is used for the manufacture of parts that have
high ductility and are operated at temperatures up to 450 °С, as
well as bushes, screws, washers and other parts subjected to
thermochemical treatment to have high surface strength with low
core strength.
Welding
No welding restrictions except for thermochemically treated parts.
Welding methods: manual metal arc welding, submerged arc welding,
electric resistance welding.
