1.4543 / X3CrNiCuTiNb12-9
Precipitation hardenable martensitic stainless steel - This precipitation hardenable martensitic stainless steel is ESR remelted. Its main attribute is its simplicity to use. Its forming is easy and the parts made out of it present a good corrosion resistance, similar to this of 15-17%Cr martensitic stainless steels. Furthermore, its stress corrosion resistance increases with the age hardening intensity. In the age hardened condition it has a high strength coupled with an excellent toughness.
The CHRONIFER 455 KL steel is well adapted to the making of medical, surgical and dental instruments, and other applications with similar requirements. Its age hardening requires a single treatment only and its aging dimensional contraction is ≤ 0.1%.
