~ 316 L (+S) 1.4427 So is available in stock as bars/rods. Chronifer Special KL, Chrome-Nickel-Molybdenium-Steel, not hardenable. Austenitic stainless steel with improved machining properties due to the content of Sulfur (S). This high quality steel is mainly designed for watch parts. Its corrosion resistance is higher than the standard Aisi 303. The Chronifer Special KL is a good compromise between machinability and corrosion resistance. Compared to our Aisi 316L Decolletage, it has less copper content (max. 0.6% considered as traces).

Brief description
Klein designation:
Chronifer Special KL
Class of metals:
Free machining martensitic stainless
steel with S addition
Standard AISI:
˜ 316 L (+S); 1.4427 So
Machinability:
good
Hardening capability:
cannot be hardened
Cold forming:
can be cold formed
Cold working:
can be strengthened by cold working
Polishing ability:
not adapted for mirror polishing
Corrosion resistance:
fair to good
Ferrite ∂ (Delta):
can exhibit traces of ∂ (Delta) ferrite
Magnetism:
can exhibit traces of magnetism
Welding:
can be welded
Uses:
components of watch movements and
for the watch exterior, and numerous
industrial applications
~ 316 L (+S) 1.4427 So is available in stock as bars/rods. Chronifer Special KL, Chrome-Nickel-Molybdenium-Steel, not hardenable. Austenitic stainless steel with improved machining properties due to the content of Sulfur (S). This high quality steel is mainly designed for watch parts. Its corrosion resistance is higher than the standard Aisi 303. The Chronifer Special KL is a good compromise between machinability and corrosion resistance. Compared to our Aisi 316L Decolletage, it has less copper content (max. 0.6% considered as traces).
