Grade of Steel for Spring Shackle Pin
#3
i guess can be made in a multi section style partly pressed together. Silver steel is through hardening not case hardening and very prone to cracking when quenched. It is sold in a medium hard state and would probably wear for years in modern well greased useage. Or with nylon bushes. Lester Reader notable NZ specvial builder and rubber duck owner used plain silver steel as kingpins in his Seven based special as less prone to fracture.
There are probably many moderately worn about which could be reground by the patient.
