| Chronifer 17-4 PH material
is Manufactured in Rod, Bar and coil
AISI 630 ~ Stainless Steel
Material Properties
Custom 630 (17Cr-4Ni) is a
martensitic precipitation/age-hardening stainless steel offering high
strength and hardness. It has good fabricating characteristics and
can be age hardened. Best machinability quality is in solution P 800
(H1150M) and P930 (H 1150)
Corrosion
This alloy withstands corrosive attack better than any of the 400 series hardenable stainless
steel, and in most applications, it's corrosion resistance closely
approaches that of Stainless Types 303 and 304.
Execution
Bars: Cold drawn, ground and
polished. Standard length of bars :3m
Surface roughness N5-N6 or in
coils for (Escomatic machines)
Tolerance
Standard ISO h7 (some sizes ISO
h8)
Heat Treatment
Hardening condition P800 or
P930 has to be solution annealed before hardening
Max obtainable hardness 44 HRC
